[R] gzfile with multiple entries in the archive

[Greg Snow]

If you know how to use the unix/linux tools already, then you may want
to look at cygwin (http://www.cygwin.com/), it allows those of us
trapped in a windows world to still lead productive lives with the
unix/linux tools.

Subject: [R] gzfile with multiple entries in the archive

If I open a tgz archive with gzfile and then parse it using readLines I
miss the initial line of each member of the archive - and also the name
of the file although the archive otherwise complete (but useless!).

 

Is there any way within R to extract both the list of files in a tgz
archive and to extract any one of these files?

 

Clearly I can use zcat and tar on Linux, but I need this to work within
the R environment on Windows!

 

Thanks

 

John James
