I often find myself making lists similar to this list(var1=var1, var2=var2) It doesn't seem list has an option, to make it use the name of the variable as name in the list. Is there another function that does this? -- Med venlig hilsen Rune Schjellerup Philosof Ph.d-stipendiat, Forskningsenheden for Biostatistik Telefon: 6550 3607 E-mail: rphilosof at health.sdu.dk Adresse: J.B.

...the second subscript anyway). Besides, I have a single value on the rhs, so it should be allowed to have NAs in the lhs, according to help(Extract). What am I missing? I can see no ambiguite as to what the result of those commands should be (j == c(2,2,NA)). -- Med venlig hilsen Rune Schjellerup Philosof Videnskabelig Assistent, Statistik, SDU Telefon: 6550 3607 Email: rphilosof at health.sdu.dk Adresse: J.B.

When I execute mclapply it creates the needed processes, but these processes never begin computing anything, they just wait indefinitely. I recently upgraded to version 2.9.1, which might have caused the problem. -- Med venlig hilsen Rune Schjellerup Philosof Ph.d.-studerende, Statistik, IST, SDU Telefon: 6550 3607 E-mail: rphilosof at health.sdu.dk Adresse: J.B.

Dear R-dev, I would like to accelerate my R computation by using parallel OpenMP compilers (e.g from Pathscale) on a 2-processor AMD server and I would like to know whether R is a tread safe library. The main kernel of the OpenMP parallelization is a C SEXP function that performs the computational routine in parallel with: ******************* SEXP example(SEXP list, SEXP expr, SEXP rho) {
