Unable to install.packages(): system call failed: Cannot allocate memory; installation of package had non-zero exit status
I figured out. I was all about the swap value.
There are several web pages that advice to decrease the default swap use in order to speed up Ubuntu. What I did to fix the problem.
In the terminal...
#Know the swap value cat /proc/sys/vm/swappiness10# Access the swap configurationgksudo leafpad /etc/sysctl.conf# Increase the swap usage to 30 (default is 60)vm.swappiness=30Then, I rebooted. And installed the packages happily without any problems.
I confirm that the problem was with RAM space. i closed some background applications and it installed smoothly without any need to reboot my system
