In [1], Mike FC has a graph where 'bzip2' and 'xz' seem > to give the best compression ratios, at least for RDS files. 'bzip2' can be surprisingly good on very repetitive payloads. It compresses 0x80000000 zero bytes to only 1.5 KiB, much better than 'xz -9' with 305 KiB (with compression settings not making much difference), although the compression is not perfect. One terabyte of zeros can be compressed to 697202 bytes of repetitive compressed stream that can be bzipped further to 248 bytes. Binary packages are probably the most obvious target for new compression methods because there is no need to install them on older versions of R. -- Best regards, Ivan ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
