How to install multicore package on R v3.1.2?

Question

I am using default command to install multicore package

install.packages('multicore','http://www.rforge.net/')

as written here http://www.rforge.net/multicore/files/ but I recieve warning:

install.packages('multicore','http://www.rforge.net/') Warning in install.packages : 'lib = "http://www.rforge.net/"' is not writable Would you like to use a personal library instead? (y/n) y Warning in install.packages : package ‘multicore’ is not available (for R version 3.1.2)

Does anybody know any solution to this? I can not use previous versions of R. I would like to use mclapply function from that package.

Thanks for help.

Answer 1

Why do you need it?

Most of its functionality has been integrated into the parallel package which already comes with R. Have a look at its vignette, eg from within R via vignette() or else from here.

And the reason you cannot install 'multicore' is because it has been withdrawn by R Core, given how its functionality is (essentially entirely) in 'parallel' now.
