gunzipundefined

Gunzip a file.

filename{Pathname of (gzip'ed) input file to be gunzip'ed.}
 destname{Pathname of output file.}
 overwrite{If the output file already exists, then if
   overwrite is TRUE the file is silently overwritting, otherwise
   an exception is thrown.}
 remove{If TRUE, the input file is removed afterward,
   otherwise not.}
 BFR.SIZE{The number of bytes read in each chunk.}
  ...{Not used.}

Returns the number of (input/compressed) bytes read.

Internally gzfile() (see connections) is used to read chunks of the gzip'ed file, which are then written to the output file.
