Statistical packages are software titles, such as JMP and GNU Octave, and programming languages, such as MATLAB, R and SAS, that are used to discover, explore and analyze data and suggest useful conclusions, either to learn something unexpected or to confirm a hypothesis. The field includes the design and analysis of techniques to give approximate but accurate solutions to hard problems in statistics, econometrics, time-series, optimization and 2D- and 3D-visualization. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.

Please look at the following VBA code that relates to the attached spreadsheet. The relevant section of this sub is the second paragraph where the first line comment is 'Delete all data in the "TME" tab older than one week. The other paragraphs of this sub work fine as far as I can tell.

This section of the sub refers to the attached sheet, which is the TME tab of a much larger workbook. As you see, the intent of this section of the sub is to delete all records on the TME sheet older than one week from TODAY (the date in column I, Row 1 or relative cell 1,9). For reference, the formula in I1 is =(TODAY()-MOD(TODAY()-1,7))-3. This formula works fine - no need to change it.

The problem is that this second paragraph of the sub below does not actually do any deleting of rows. It also does not stop execution for any errors, but proceeds right on to the next section of the sub without doing anything. I want it to delete all rows from row 2 of the attached sheet and continue deleting until the date in column A is one week older than the date in cell I1.

What needs to be changed to this section of the sub to get it to properly delete the required rows?

Thanks!

I need to ensure ALL mandatory cells in a row are filled in before another row is added.  Please see attached file for example.  
I've intentionally left blank columns I, O, R and S.  
Before I add a second row, I'd like to see an error message identifying the unfilled cells, or even better those unfilled cells highlighted.
If this is not able to be done, any suggestions are most welcome.

Hi,

Im hoping someone can help me. I have the below code with I am using to take screenshots and open up a draft email in Excel with the screenshot in the main body. But the screenshot is really small. I think this is to do with the actual Excel sheet been zoomed to 70% but it doesn't change when I set it back to 100%. Is there any way of writing in the code, or can someone amend my cose so it resizes the picture? The code is...

Private Sub CommandButton1_Click()
'Copy range of interest
Dim r As Range
Set r = Range("B3:N40")
r.Copy

'Paste as picture in sheet and cut immediately
Dim p As Picture
Set p = ActiveSheet.Pictures.Paste
p.Cut

'Open a new mail item
Dim outlookApp As Outlook.Application
Set outlookApp = CreateObject("Outlook.Application")
Dim outMail As Outlook.MailItem
Set outMail = outlookApp.CreateItem(olMailItem)

'Get its Word editor
outMail.Display
Dim wordDoc As Word.Document
Set wordDoc = outMail.GetInspector.WordEditor

'Paste picture
wordDoc.Range.Paste
End Sub

Hey guys,

We're in the middle of migration to Office 365. We moved a lot of users already mostly through ECP on Office 365. Then we decided to move some users Archives only first and it was working just fine. So, when we try to move the user's  primary mailbox for users who already have Archive Online migrated earlier - it gives us following error:

[PS] C:\Windows\system32>New-MoveRequest -id "user@domain.com" -Remote -RemoteHostName "email.domain.com" -Target
DeliveryDomain domain.mail.onmicrosoft.com -RemoteCredential $LocalCredential -primaryonly
Target user 'User' already has a primary mailbox.

Not sure where the error is. User's primary mailbox still on premises. And Archive is online. User can access both from Outlook. ECP on Exchange don't have this user as a recipient. When I run Get-MailboxStatistics I see that user still on-prem and only archive on Office 365

Hi,

I have attached a spreadsheet with some code and functions, but I want to know if I can achieve the following.

Spreadsheet has 7 tabs.  The tabs I am interested in is tabs 2 - 7

Each tab has one row of data.  Now if you go to tab 2 - Risks, the go to column J and in the dropbox click Action.  You will now see that the row has gone.

Go to the Action tab, and you will see that the row appears here, and that is correct.  I column B you will see an R.  As it was moved from the Risk tab, it was enetered as a R for Risk.  But as it now resideds in Action, I want the cell automatically update to an A.

This movement and changes will only aplly for rows that move between Tabs 2-4,  Risk, Action, Isse and Dependancy.

Please let me know if any more info is needed.

These are the codes that are currently working in pulling up the data.
Me.ADDRESS.Value = Sheet1.Range("Ax" & r).Value
Me.ADDRESS.Value = Sheet1.Range("Aw" & r).Value
Me.REMARKS.Value = Sheet1.Range("AY" & r).Value
Me.Image1.Picture = LoadPicture(Worksheets("Sheet1").Range("AZ" & r))  'Where r is the row number

Now I am using these codes to update the file.
Sheet1.Range("AV" & r).Value = Me.RELATION.Value
Sheet1.Range("AW" & r).Value = Me.MOBILE1.Value
Sheet1.Range("AX" & r).Value = Me.ADDRESS.Value
Sheet1.Range("AY" & r).Value = Me.REMARKS.Value
(Need code for the update of picture here....)
I tried these code to update the picture but it won't work.
Worksheets("Sheet1").Range("AZ" & r).picture=me.loadpicture.image1
I already tried to invert but still its not working.

I have what I thought was a well prepared dataset.  I wanted to use the Apriori Algorithm in R to look for associations and come up with some rules.  I have about 16,000 rows (unique customers) and 179 columns that represent various items/categories.  The data looks like this:

Cat1  Cat2  Cat3  Cat4  Cat5 ... Cat179
1,        0,       0,        0,      1,     ...  0
0,        0,       0,        0,      0,     ...  1
0,        1,       1,        0,      0,     ...  0
...

I thought having a comma separated file with binary values (1/0) for each customer and category would do the trick, but after I read in the data using:

>data5 = read.csv("Z:/CUST_DM/data_test.txt",header = TRUE,sep=",")

and then run this command:

> rules = apriori(data5, parameter = list(supp = .001,conf = 0.8))

I get this error:

Error in asMethod(object):
column(s) 1, 2, 3, ...178 not logical or a factor. Discretize the columns first.  

I understand Discretize but not in this context I guess.  Everything is a 1 or 0.  I've even changed it from INT to CHAR and received the same error.  I also had the customer ID (unique) in column 1 but I understand that isn't necessary when the data is in this form (flat file). I'm sure there is something obvious I'm missing - I'm new to R.

What am I missing?  Thanks for your input.

Hello, needing some help here.

Cell Sheet5 B13 and C13 has values that represent temperature and dewpoint in Fahrenheit.  I need to convert each value into Celsius, the formala is 5/9*(Temp-32).  Then for the first value I need to use this formula 6.11*10.0**(7.5*Tc/(237.7+Tc)), where Tc is the value.  Then for the second value I need 6.11*10.0**(7.5*Tdc/(237.7+Tdc)), where Tdc is the second value.  Finally I need to divide the number from the second equation by the number in the first equation and times it by 100.

Finally, I need to computer =16.923+(Temp*1.85212*(10^-1))+(5.37941*RH)-((Temp*RH)*1.00254*(10^-1))+((Temp^2)*9.41695*(10^-3))+((RH^2)*7.28898*(10^-3))+((Temp^2)*RH*3.45372*(10^-4))-(Temp*(RH^2)*8.14971*(10^-4))+((RH^2)*(Temp^2)*1.02102*(10^-5))-((Temp^3)*3.8646*(10^-5))+((RH^3)*2.91583*(10^-5))+(RH*(Temp^3)*1.42721*(10^-6))+((RH^3)*Temp*1.97483*(10^-7))-((RH^2)*(Temp^3)*2.18429*(10^-8))+((RH^3)*(Temp^2)*8.43296*(10^-10))-((RH^3)*(Temp^3)*4.81975*(10^-11)).  Temperature is the original Fahrenheit value and RH is what we calculated above.


Trying to shoot for some type of function as I will need to use this to calculate multiple cells.  Thanks in advance for you help.

On linux I have an arbitrarily sized file file of k lines (say 500,000 lines) and I want to randomly delete  lines in the file until I have r (say 10,000) lines remaining.  How can I do this with a Linux shell?

Basically, I have a data set and I want to reduce it to a more manageable sample.

Hi,
I am wondering what program could be used for the attached project.
I'm wanting to find what variable weightings produce the maximum profit.
Is this a form of regression and if so which one ?
Please manually input values into cell range M2:S2 and notice how it affects P/L cell (Yellow)

Many thanks for any advice you may have

Hi,
I have a spreadsheet where a User keeps track of numbered Jobs.
The current Userform can be updated with more information as Jobs progress.

Is there any way to write back the data in a different font or colour ?
We want to use "strikeout" font on cancelled Jobs (rather than have a new field in the spreadsheet).
I will put a "cancelled Job" button on the Userform for this purpose (with all the appropriate controls).

Example of current code to write back data is:

r = worksheetfunction.match(Val(JobBox), Ws.columns(1), 0)
currentrow = r
Me.firstnamebox = ws.cells(r, "b")
Me.lastnamebox = ws.cells(r, "c")
Me.Phonebox = ws.cells(r, "d")
Me.AgeBox = ws.cells(r, "e")
....etc,etc

So I'm trying to put together a website to display analytics that are output from R Studio.  I'd like to keep the same masterpage and basic site design that we have on our other company sites which are all ASP.Net...   Any ideas on how I can programmatically accomplish this, these reports will be generated daily.  I know this is a broad question but all of my searches have left me unsure how to accomplish this.  Deadlines Friday, so...  =D  Even a basic direction at this point would be greatly appreciated.  I basically want to have the HTML page hosted within my ASP Masterpage as if they were one page.  Any ideas?

Guys,I am trying to get this piece of code working but I know its wrong but cant think how to fix it

What I want it to do is look at the cell in column D and compare the result of the formula which is a look up and if they match then to not colour the cell but if they don't then I want it to colour the cell.

Sub LoopFormula()

On Error GoTo myError

LastRow = Cells(Rows.Count, "A").End(xlUp).Row

For r = 3 To LastRow

If (Sheet2.Cells(r, "D")) = "=IF(D3=VLOOKUP(D3,Project!$A$2:$A$3000,1),VLOOKUP(D3,Project!$A$2:$A$3000,1))" Then Sheet2.Cells(r, "D").Interior.ColorIndex = xlNone
If (Sheet2.Cells(r, "D")) <> "=IF(D3=VLOOKUP(D3,Project!$A$2:$A$3000,1),VLOOKUP(D3,Project!$A$2:$A$3000,1))" Then Sheet2.Cells(r, "D").Interior.ColorIndex = 3

Next

Exit Sub
myError:

MsgBox ("Error"), , "Error"

End Sub


Any help

Hi All,
Would you recommend a website(s) where it will show me the condensed basics of college level statistics in laymen’s terms – so that quickly I can understand the core and key concepts? and apply those conceptas in real life  
Thank you
