[R] speed in batch mode versus interactive mode

[karl cottenie]

Hello R-users,

is there a speed gain in submitting R code in batch mode as opposed to
the normal interactive. I searched the R website and the archives, and
only found a reference R-data.html that "to read in very large objects
it may be preferable to use the dumpfile as a batch script rather than
source". Is this true for any R code on both Windows and Linux systems,
and how much speed improvement can be gained (5 % or maybe 20 %)?

thanks,

Karl
