I am using *R version 3.0.2* (2013-09-25) on Ubuntu desktop (*Ubuntu 14.04.4 LTS*). I am running *var model *on a matrix with 199 columns and 604800 rows. The server has 12 core and 32GB of memory. When the model is running, i checked CPU and Memory consumption using 'htop' linux command. I observe all the cores are being used and memory memory usage is on average 17GB out of 32GB. After running the model for about an hour, the system kills the R process. Following the output:
*> library("vars")* *> vmodel=VAR(only_variables_without_missing, p = 1, type ="both")* *Killed* Please help.
