Although I along with the other believe there probably is an efficient R
solution, the answer to your direct question can perhaps be found at
http://www.fortran.com/.  The  free GNU G95 fortran compiler is at

Subject: [R] Question about multiple regression

Dear R-list,
maybe some of you could point me in the right direction:

Are you aware of any FREE Fortran or Java libraries/actual pieces of
code that are VERY efficient (time-wise) in running the regular linear
least-squares multiple regression?
More specifically, I have to run small regression models (between 1 and
15 predictors) on samples of up to N=700 but thousands and thousands of

I am designing a simulation in R and running those regressions and R
itself is way too slow. So, I am thinking of compiling the regression
run itself in Fortran and Java and then calling it from R.

Thank you very much for any advice!
