If I have a R script written under windows I encounter sometimes the problem that function names are not the same as in linux. See  zip.unpack which works perfectly under windows but not under linux. Is there a better method to find functions named different in different OS than asking the mailing list? 

There are 2000+ function in 'base R'. Most of them are portable. Many of us
who have been writing portable code know which ones to avoid.

In a first instance, your best best is almost always the builtin-help,
e.g. help(rnorm) will be the same on all system.

Some things are by their very nature more OS-dependent, but R does a pretty
good job of abstracting most of it away ....

As for zip.unpack, it would appear that R on Linux does not have it. I see
zip.file.extract so maybe you can use that.

When I encounter a function which is not in R linux what is the best way to find the right linux function for it? So next time I can help myself. I browsed the web for a long time and could not find anything to the the function
