How to check the amount of RAM in R

r ram

Given the warnings concerning platform-dependency discussed in the earlier comment, you could for example parse /proc/meminfo on Linux:

$ grep MemFree /proc/meminfo MemFree:          573660 kB$ awk '/MemFree/ {print $2}' /proc/meminfo 565464

You could try the second approach via system(..., intern=TRUE), or even via a pipe connection.

Edit some 5+ years later: In R, and just following what the previous paragraph hinted at:

R> memfree <- as.numeric(system("awk '/MemFree/ {print $2}' /proc/meminfo", +                               intern=TRUE))R> memfree[1] 3342480R>

r ram

Now you can do that with benchmarkme::get_ram function.

r ram

I would recommend using memuse::Sys.meminfo().
