I have a run_stat.r script that can run in command line such as Rscript anova.r on my ubuntu server: 

#load package   
library(ez)  
#run code....

The problem is that the loading time of ez package would take 2~3 seconds.

Can R preload the package one time, so that it doesn't need to re-load the same package every time I run the script? Any suggestions to speed up the loading time of the package?

  • This http://stackoverflow.com/questions/10300769/how-to-load-packages-in-r-automatically may help you. – Fernando Mar 21 '17 at 16:54
  • Thanks. But I've already seen this post. It just "auto-load" the package when R start. What I want is something like the "shared session". I'm not sure if R support something like this? – David.Z Mar 21 '17 at 17:00
