Is it just me, or did a corrupt PACKAGES.gz file get installed in the bin/windows/contrib/3.2 directory of CRAN mirrors recently? gzfile() complains about it and Cygwin's gzip cannot decompress it. I tried the following
repos <- "https://cran.rstudio.com"; v <- "3.2" pkgs.gz <- paste(sep="/", repos, "bin/windows/contrib", v, "PACKAGES.gz") tfile <- tempfile(fileext=".gz") download.file(pkgs.gz, dest=tfile) r.gz <- readLines(gzfile(tfile, "r")) tail(system(paste("c:\\cygwin\\bin\\gzip -d - ", shQuote(tfile)), intern=TRUE)) and got > repos <- "https://cran.rstudio.com"; > v <- "3.2" > pkgs.gz <- paste(sep="/", repos, "bin/windows/contrib", v, "PACKAGES.gz") > > tfile <- tempfile(fileext=".gz") > download.file(pkgs.gz, dest=tfile) trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.2/PACKAGES.gz' Content type 'application/x-gzip' length 188174 bytes (183 KB) downloaded 183 KB > r.gz <- readLines(gzfile(tfile, "r")) Warning message: In readLines(gzfile(tfile, "r")) : seek on a gzfile connection returned an internal error > tail(system(paste("c:\\cygwin\\bin\\gzip -d - ", shQuote(tfile)), intern=TRUE)) [1] "" "gzip: stdin: unexpected end of file" Warning message: running command 'c:\cygwin\bin\gzip -d - "C:\Users\wdunlap\AppData\Local\Temp\RtmpG42jk4\file2a201a9e4802.gz"' had status 1 R's gz code seems to recover from the bad seek, but Cygwin's gzip cannot. > pkgs <- paste(sep="/", repos, "bin/windows/contrib", v, "PACKAGES") > r <- readLines(url(pkgs, "rt")) > all.equal(r, r.gz) [1] TRUE I get the same results using the Spanish miror, https://ftp.cixug.es/CRAN Bill Dunlap TIBCO Software wdunlap tibco.com [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
