Try the fork() function in the package multicore (if your system supports it)

Subject: [R] R in batch mode packages loading question


I use R in batch mode. Each time, I execute a script, R is loading each packages I need in my script. That's Ok But, I had to execute many scripts , and each time R is re-loading the corresponding packages, which take to much time

Is it possible ask R to load the packages only once, and stay in memory in background for further scripts, which would avoid to load the packages in each script, or if you have another solution that need to only load packages once in the first scripts, so that further scripts do not need to load these packages too.

Thanks in advance
