Hi, I am installing a lot of packages to a new R installation and it takes a long time. However the machine got 4 cpus and most of the packages are written in C/C++. So is it possible to add a -j4 flag to the make command when I use the install.packages() function? That will probably speed up the package installation process 390%.
See the Ncpus argument in ?install.packages.
Thanks. However it looks like Ncpus=4 tries to compile four R packages at the same time using one cpu for each packages.
