Hi, We've written an R program to conduct a series of analyses on a data file that is a comma separated value file. At one time it worked, but every since having down loaded the new version of R, I'm getting the following: Cannot open c:windowsdesktopslope.csv What I've asked the program to do is to open a datafile using the following: DataFile<- 'c:\windows\desktop\slope.csv' So it is clearly stripping the "\" from the path. I've tried using "/" to no avail. Any suggestions? Paul Paul J.

On Windows, you need to use "\\" instead of a single "\".
To avoid this
problem in the future (and to be platform independent), you might consider
doing:
DataFile <- file.path("c:", "windows",
"desktop", "slope.csv")
which will insert the appropriate directory separator for you.
