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%. Regards Martin M. S. Pedersen
How to add make option to package compilation?

See the Ncpus argument in ?install.packages. Duncan Murdoch

Thanks. However it looks like Ncpus=4 tries to compile four R packages at the same time using one cpu for each packages.

But you said you had lots to install so would that not speed things up too?
From the documentation:
"
Ncpus: the number of parallel processes to use for a parallel
install of more than one source package. Values greater than
one are supported if the ?make? command specified by
?Sys.getenv("MAKE", "make")? accepts argument ?-k -j Ncpus?

The variable MAKE is defined in ${R_HOME}/etc/Renviron, and can be
over-written with ~/.Renviron
MAKE=make -j
There is further discussion in
https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Configuration-variables
and ?Renviron.
One could configure a source installation to always compile with make
-j, something like ./configure MAKE="make -j"
