[R] Problem importing file in R after switching from windows to Ubuntu

[Christian De Santis]

Thanks for your reply Ista and Duncan, 

i solved the issue and you were both right. Ista, my file was spelled with a capital L (as in "Light") and it wasn't recognized. However, this was never a problem in windows as Duncan pointed out. You live and learn. :-)

Thanks very much,
Christian

I have copied my working folders into Ubuntu and changed the WD and the \\ into /. I tried to re run the script and it was going all well till i tried to read a csv database into R.

Likely Ubuntu is treating the file system as case sensitive; Windows
usually does not.

Another possibility is that you don't have read permission on the file.
