I am automating some webscraping with R
in cron
and sometimes I use R CMD BATCH
and sometimes I use Rscript
.
To decide which one to use I mainly focus if I want the .Rout
file or not.
But reading the answers to some questions here in SO (like this or this) it seems that Rscript
is preferred to R CMD BATCH
.
So my questions are:
Besides the fact that the syntax is a little different and R CMD BATCH
saves an .Rout
file while Rscript
does not, what are the main differences between the two of them?
When should I prefer one over another? More specifically, in the cron
job above mentioned, is one of them preferred?
I have not used yet littler
, how is it different from both Rscript
and R CMD BATCH
?
From what I understand:
R CMD BATCH:
Rscript:
littler:
