How to install a multi-core package on R v3.1.2?

Question

I use the default command to install the package multicore

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

as written here http://www.rforge.net/multicore/files/ , but I get a warning:

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

Does anyone know a solution? I cannot use previous versions of R. I would like to use the function mclapplyfrom this package.

Thanks for the help.

Why do you need this?

Most of its functions have been integrated into the package parallelthat already comes with R. Look at your vignette, for example, inside R via vignette()or from here .

And the reason you cannot install "multicore" is because it was removed by R Core, given how its functionality (essentially completely) is now "parallel."
