I guess because I've never seen source tarballs distributed as .xz files but it's good to know that 'R CMD build' and 'R CMD INSTALL' support that. So let me reformulate my question: do CRAN have any plans to switch from .tar.gz to .xz for the distribution of source tarballs? Is this something that tools like write_PACKAGES(), available.packages(), and install.packages() would be able to handle? Would they be able to handle a mix of .tar.gz and .xz packages? (Which would be important for a smooth transition from .tar.gz to .xz across CRAN/Bioconductor.) I'm just trying to get a sense if the effort to reduce bandwidth will go beyond the distribution of R source snapshots.

R CMD INSTALL happily installs .tar.xz files, and the name is not used to detect compression so .tar.gz files could be bzip2- or xz-compressed. Note that tarball compression is pretty much irrelevant where the tarball contains large compressed files, for example .rda files or vendor.tar.xz files of Rust sources. You have to arrange that the first compression is the bast possible. -- Brian D.

Hi Martin, Sounds good. Are there any plans to support the xz compression for package source tarballs? Thanks, H.

[Rd] FYI: daily R source tarballs from ETH: *.xz instead of *.bz2)
A quick notice for anyone who uses cron-like scripts to get R source tarballs from the ETH R/daily/ s: I've finally switched to replace *.bz2 by *.xz which does save quite a bit of bandwidth. Currently, you can see the 2 day old *.bz2 (and their sizes) and compare with the new *.xz one (sorted newest first): https://stat.ethz.ch/R/daily/?C=M;O=D Best, Martin __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
