Hi, I am getting the following error:
Error in if (any(scaleValue == 0)) { : 
  missing value where TRUE/FALSE needed

Open in new window


How can I fix it?  Thank you.

my code:
library(caret)
# read data
features.adj.dfm1<-read.table("features_adj_dfm1k.txt",sep=" ",header=T,stringsAsFactors=F)

###### error after this function
trans<-preProcess(features.adj.dfm1,method=c("BoxCox","center","scale"),na.remove=T)

Open in new window

That text file is massive, and too big to read on my phone. All I see is a lot of numbers.

From your first Code showing the error it is telling you that the if statement is malformed.
It should be of the form:
If (condition, what if true, what if false)

Your second code entry doesn't show the line with that if statement.

As you have included an Any () statement in the if, I would suggest that you have miscounted the brackets and closed the if without including the true/false parameters.

you will need to post that actual line for me to check fully, but you can probably find it yourself if you count the braces.
