Hi, all. I began to migrate my R codes from Windows to Linux and surprised me with an old question. I simplified the problem and made a little test to compare times at same computer and the Linux time is worse (not so little) than Windows time: 28 vs 53 seconds. I make an example (below) to facilitate all to see the difference. I also build from source (it's my first time) a version of R to

I'm implementing a function to compute the moore-penrose inverse, using a code from the article: Fast Computation of Moore-Penrose Inverse Matrices. Neural Information Processing - Letters and Reviews. Vol.8, No.2, August 2005 However, the R presents an error message when I use the geninv. The odd thing is that the error occurs for some arrays, however they have the same size. And the R

I want to plot quantitative data as a function of three two-level factors. How do I group the bars on a barplot by level through labeling and spacing? Here <http://www.thomaslevine.org/sample_multiple-factor_barplot.png>'s what I'm thinking of. Also, I'm pretty sure that I want a barplot, but there may be something better.
