[R] Linux-Windows problem

Its not an R problem, but an editor problem (therefore slightly off-topic I admit).  I do most of the coding in Windows and somestimes the Rkward editor (in linux) will not open the file and it tells me it cannot determine the encoding.  If I try to source that file into R (in the linux version) I sometimes get an unexpected character on line such and such, but I don't see any problem and the code runs fine in windows.  The fix, I discovered is to open the file in notepad (in windows) and resave it.  Then Rkward will open it just fine.  

I am sure there is an easy setting I can change to make the two work more smoothly together, but I just haven't found it yet.

Thanks,

Roger

Sorry for asking the obvious, but have you confirmed that you are running the same version of R on both systems?
