Rstudio not using swap memory


I am running Rstutio in Ubuntu Linux and I am trying to run a process that requires more RAM than I have. I have 32GB and to increase it I was allocating 12GB in swap memory. However, while I can see the swap memory with free -m in terminal, Rstudio does not seem to be using this and crashes soon after the RAM reaches usage 30Gb.

The Rstudio memory usage report shows this:


Does anyone know how can I make it use swap memory?

The way I increased my swap memory was this:

# Swap memory change - linux ubuntu
# following

# check space

free -m

swapon -s

# create 10G swap file
sudo fallocate -l 10G /swap_file

# secure swap file
sudo chmod 600 /swap_file

# enable swap area on file
sudo mkswap /swap_file

# Extend Swap Space
sudo swapon /swap_file

# check space

free -m

swapon -s
