[Rd] Named backreference in gsub()?

Hi, I'm running out of the *numbered* backreferences \\1, \\2, ..., \\9 for gsub(). Does R support *named* backreferences, and if so, what is the syntax? Thanks Henrik __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-deve

I hope you will forgive a serious comment on this thread, but the new "sos" package makes "greping through the headers" shockingly easy. It returns the 'RSiteSearch( ___ , "function")' information in a data.frame of class "findFn" sorted to put the package with the most matches first. Du

[Rd] Multicore bootstrap

Bootstrapping can easily be sped up on multicore machines using parallel processing of the seperate bootstraps. As a proof of concept I slightly modified the boot.sem function to use multiple cores, using mclapply from the multicore package. Example code can be found on my website: http://www.jer

[Rd] suggest enhancement to segments and arrows to facilitate horizontal and vertical segments

I suggest a simple enhancement to segments() and arrows() to facilitate drawing horizontal and vertical segments -- set default values for the second x and y arguments equal to the first set. This is handy, especially when the expressions for coordinates are long. Compare: Segments: < function (x
