Re: [R] Behaviour of R with win98 and XP?

What are you doing that creates a file path c://Temp//TempFile.csv? That is not a valid path under Windows: use / not // or, better, use file.path(). As far as I recall NT-based systems accept empty path elements and W98 does not.

If this is really R 1.6.1, you are way overdue for an upgrade.

Not in this way, but W98 behaves differently from XP in many ways.
