R for Astronomers
type: item
description: Folks, I not *really* advocating we all give up IDL for R, but there are some things R does better than IDL. And, I readily admit, there are a *ton* of things IDL does better than R. But R does show up in the strangest places these days. Here is a site that came to my attention this morning that has tips for astronomers. http://www.sr.bham.ac.uk/~ajrs/r-project.html It might be worth having a look.

IMHO, R beats IDL hands down for ease and quality of plots. And for statistics, well, that's what it is for. I've never even considered using IDL for mixed-effect modeling. But I still use IDL for many, many things. Computer languages are not quite like marriage - I think it is acceptable to be in serious relationships with more than one at a time. Of course juggling multiple relationships is fraught with danger - witness my continual print, x in R and print(x) in IDL... Mike

For big blobs of data that can be a real pain. It would be a mistake, however, to think that R can't pass by reference. I won't pretend to understand how it works, but some of the clever R authors have developed techniques to employ pass-by-reference in R. One example is the pretty-easy-to-use R.oo (http://www1.maths.lth.se/help/R/R.oo/), but there are other examples in R. > But I > still use IDL for many, many things.

Another is IDL>source("my_program.pro") and R>.compile "my_program.r" Argh! Cheers, Ben
