R trick - using Rscript with command-line parameters

[gusl]

doPlots <- TRUE; doPdflatex <- TRUE ##default settings
args <- commandArgs(TRUE)
if (length(args)>0) {
  eval(parse(text=args[1]))
}

The idea is that, since we using R's reflection mechanism, we can change the variables from the command-line.

Rscript fix-multiple.R "doPlots=FALSE; doPdflatex=FALSE"

(You could also theoretically write code that actually does stuff, but that would be strange)

Keen! Forwarded to the lab mate. Will definitely think about this for future R scripts.
