Dear Prof. Ripley:
Thanks very much.
The "getZipInfo" function in the "Rcompression" package gave me
information on all of the files in my zip file, as you suggested.
Then "unzip" in the "memisc" package extracted the desired file
and returned a character string giving the name of that temp file, which
I could then use in "readLines" or some other function.
Thanks again,
Spencer Graves

Hi, All:
How can I get the list of files contained in a zip file?
"zip.file.extract" will extract a specific 'file' from 'zipname',
but how can I get the names of the files in 'zipname'?
Package Rcompression will I believe allow you to do this. (An
Omegahat package, with a Windows binary on CRANextras.) R itself does
not contain code to do so.
Another approach is to call system("unzip ....", intern=TRUE) and
process the result.
