I have received some code in R but when I run the code, I get the the following message at the end
Error in file(file, ifelse(append, "a", "w")) :
cannot open the connection
In addition: Warning message:
In file(file, ifelse(append, "a", "w")) :
cannot open file 'ptr.txt-3R.res': Permission denied
There is therefore a result file, but it cannot be opened!
I am supposed to get graphs as well as results, but I only get some results with no graphs which is suspect need to access the result file?
Why would it not be able to access the result file?
I am totally novice in R and rally lost as this code works perfectly in one of my colleagues desktop!
