Linux-Windows problem

Sorry for asking the obvious, but have you confirmed that you are running the same version of R on both systems?
Since the question was about the Editor, I doubt the R version is related.

Uwe, I suspect I might be having a similar problem as the R code I generate in Windows editor (Tinn-R) doesn't always open properly in my Linux editor (Rkward), but I don't know how to change the default encoding in either one.
I am neither using Tinn-R nor Rkward, hence I cannot give any advice here. Uwe
In R on both machines, getOption("encoding") returns "native.enc", so
the problem is not with R, but rather at the OS or editor level. If you
or anyone could help me out that would be appreciated.
Thanks,
Roger

Dear All, I faced the following problem. With the same data.frame the results are different under Linux and Windows. Could you help on this topic?
I guess you read in the data differently since you have different default encodings on both platforms (e.g. latin1 vs. UTF-8) and you data is probably not plain ASCII. Best, Uwe Ligges
Thanks in advance, Ildiko Linux:
