Alternative to R's `memory.size()` in linux?

Question

R\'s memory.size() is a Windows only. For other functions (such as windows()) the help page gives pointer to non-windows counterparts.

Answer 1

Yes, memory.size() and memory.limit() is not working in linux/unix. I can suggest unix package.

To increase the memory limit in linux:

install.packages("unix") 
library(unix)
rlimit_as(1e12)  #increases to ~12GB

You can also check the memory with this:

rlimit_all()
