r - How to set memory limit in RStudio (desktop version)?

Question

I'm aware that there has already been a similar question here, but the answer is out-of-date. The information I've found in the internet refers to RStudio Server rather than Desktop.

I have limited resources on my Windows 7 x64 PC. I've set the environment variable R_MAX_MEM_SIZE and this is accepted by the RGui (as seen when typing memory_limit()). However, RStudio (Version 0.98.507) ignores this setting and still uses the entire memory of my computer which sometimes leads to crashes of the whole system. How can I limit the amount of memory used by R when running it in RStudio Desktop?

Answer 1

This works for my PC :

 # Check memory limit
   memory.limit()
 # Change memory limit
   memory.limit(size = 15000)
