I have installed amazon free trial linux t2.micro instance , and I installed RStudio , but when I try to install packages on RI get this error:

Warning in install.packages :
system call failed: Cannot allocate memory
Warning in install.packages :

Even when I run a simple in R.

I get the same error:

system call failed: Cannot allocate memory

Answer 1

The problem is with the t2.micro instance. It has only 1GiB of Memory.

Choosing a larger instance would be the appropriate solution here. If you want to stick with the Free Tier eligible instance ( t2.micro ), one possible solution would be is to add some swap space .

Create a swap file for 1G (increase the value of count accordingly to increase the swap file size)

dd if=/dev/zero of=/swapfile bs=1M count=1024
mkswap /swapfile
swapon /swapfile

And, add this entry to /etc/fstab

/swapfile swap swap defaults 0 0
