High performance R

I have tried the solution using Intel MKL, and for me the speedup was negligible. This was for a script that does Markov-chain Monte Carlo studies of traits related to mating on a moose population. The libraries plyr, MuMIn, gdata, parallel and MCMCglmm were used. Does anyone have experience with significant speedupt using MKL? Perhaps in applications using lots of linear algebra? --AsmundEr (talk) 08:22, 25 August 2014 (UTC)Reply[reply]

I think the section on optimized builds should be dropped from the wiki, or moved to a less proninent location. openblas commonly causes problems with R HPC packages for parallel computations, and the r-mkl AUR package has been orphaned due to licencing issues. In short getting an optimized blas working with R is a fairly advanced and error-prone process, and I don't think it should be the second thing people see when they look up R on the Archlinux wiki.

Since there was no objection here I've moved the "Optimized package" section to the end. Izahn

Also there seems to be some evidence that MKL does not severely outperform OpenBLAS: Benchmarking Single- and Multi-Core BLAS --Matmo (talk) 20:13, 22 January 2016 (UTC)Reply[reply]

R CMD check problems with LaTeX

When creating packages you need to run the command R CMD check 'package-name' to check for errors. Using the arch R install, the process fails with a message

LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! LaTeX Error: File `Rd.sty' not found.

The problem seems to be that the arch R installation puts Rd.sty in

/usr/share/texmf/tex/latex/Rd.sty

whereas R CMD check is looking for it in

/usr/share/R/texmf/tex/latex/Rd.sty

It may be possible to set a switch to tell R where it is, but I just created a /usr/share/R/texmf and copied it over, including

/usr/share/R/texmf/bibtex /usr/share/R/texmf/bibtex/bib /usr/share/R/texmf/bibtex/bib/RJournal.bib /usr/share/R/texmf/bibtex/bib/Rnews.bib /usr/share/R/texmf/bibtex/bst /usr/share/R/texmf/bibtex/bst/jss.bst /usr/share/R/texmf/tex /usr/share/R/texmf/tex/latex /usr/share/R/texmf/tex/latex/omscmtt.fd /usr/share/R/texmf/tex/latex/omsaett.fd /usr/share/R/texmf/tex/latex/Rd.sty /usr/share/R/texmf/tex/latex/jss.cls /usr/share/R/texmf/tex/latex/omsaer.fd /usr/share/R/texmf/tex/latex/ts1aett.fd /usr/share/R/texmf/tex/latex/ts1aer.fd /usr/share/R/texmf/tex/latex/Sweave.sty

just to cover all bets with respect to creating vignettes, etc.
