R help - Jan 2009 - directory of files in a zip file?

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'? 

      Thanks,
      Spencer

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.
