Hi, I met similar problems when installing packages from CRAN.
It seems to be related with the function gzfile, which used by read.dcf I tried the following command, > read.dcf(system.file("DESCRIPTION", package="lattice"), "Package") Error in read.dcf(system.file("DESCRIPTION", package = "lattice"), "Package") : Line starting 'P ...' is malformed! > thefile <- gzfile(system.file("DESCRIPTION", package="lattice")) > read.dcf(thefile, "Package") Error in read.dcf(thefile, "Package") : Line starting 'P ...' is malformed! > thefile <- file(system.file("DESCRIPTION", package="lattice")) > read.dcf(thefile, "Package") Package [1,] "lattice" Sincerely, Chenliang Xu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
