...pressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress a long string than to write the whole string to the hard drive and then read it back (not to mention the saved hard drive space). I have tried accomplishing this task using memCompress() and memDecompress() without success. It seems memCompress can only convert a character vector to raw type which cannot be treated as a string. Does anyone have ideas on how I can go about doing this, especially using the standard base packages? Thanks!, Erik > sessionInfo() R version 2.11...

Hi, I get the same error as mentioned in http://r.789695.n4.nabble.com/error-in-memCompress-in-make-check-td3318922.html I try to compile R 2.12.2 under Tinycore 3.5.1 running in VirtualBox 4.0.4. Since first xz was not installed I must have used the internal version which comes with the R source tar ball. But after installing the xz 5.0.0 extension the error remained. Any idea what el...

Hi, I have zlib compressed strings (example is attached) and would like to decompress them using memDecompress ... I try this: > connection <- file("compressed.txt","r") > compressed <- readLines(connection) > memDecompress(as.raw(compressed),type="g") Error in memDecompress(as.raw(compressed), type = "g") : internal error -3 in

...the other platforms use anyway. On my AIX7 VM I'm running out of memory in xz when lazy-loading is enabled which his odd - the VM has 4Gb which one would think should be enough. The symptom is that installing MASS fails when creating lazy-load rds or the same happens when running make check as memCompress() test for xz fails. I wish there was a way to disable xz altogether.. I'd like to get IBM compilers to work first since those are the official ones. I may try gcc later, but I'm really interested in the IBM ones because that gives us a good non-GNU test (e.g., TRE fails in JIT due some al...

Simon - which compiler)s) did you use: xlc and xlfortran, or gcc/gfortran? I have made some changes to configure(.ac) so maybe my problems are self-inflicted. But would be good to know what environment you are using. Thanks for looking - and
