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.
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

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.
