[R] Writing R-scripts

[Jeff Newmiller]

A) You should (re)read the posting guidelines, and pay particular attention to supplying reproducible examples. (Not your whole script.. just a cut down version that others can run that exhibits the problem.)

B) Perhaps you should reconsider the task you have set yourself. You seem to be writing an interpreter of sorts... R is already an interpreter. Why not write a line or two in R, calling on libraries and/or sourcing a file of your own convenience functions as needed instead of encoding your wishes in arcane "testtype" values?
