[R] Behaviour of R with win98 and XP?

[Prof Brian Ripley]

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.
