This function creates zip archives, either of single files, multiple files, a single directory, multiple directories, or combinations of files and directories. Currently, recurse=TRUE, which you'll only want to disable if you really don't want directories to be recursed into (ie it's ok to leave recurse=TRUE if you only have a bunch of files to compress.)

1	zip(x, zip.file, recurse = TRUE, store = FALSE, quiet = TRUE)

`x`	a vector of file or dir names.
`zip.file`	the name (including the path) of the zip file to be created. Should end in .zip or .ZIP
`recurse`	logical: recurse into directories? (-r)
`store`	logical: store only? (-0), i.e., do not compress.
`quiet`	logical: quiet operation (-q)

none. a zip file archive is made.

If you specify a vector of filenames, if they are not all in the same directory, then the resulting archive preserves those different directory paths. i.e., when you unzip the archive, you will get a minimal representation of the filesystem that captures the different paths of the files. You should copy files into the same directory, then zip them if you do not want this behaviour! NB this copies the default behaviour of using zip on the command line. Tested on OSX using Zip 2.32 from the Info-ZIP team, which exists at /usr/bin/zip both on OSX (10.5), and solaris 10.

just like options("unzip"), implement an options("zip")
