scoping

[Paul Gilbert]

Can Luke Tierney's recent S-new post on scoping be included in the R FAQ?

I'm just going through my package and eliminating a few instances of "eval" as I
hadn't realized the dangers. I noticed that one way I've used eval is for
prompting, as in

n <- eval(parse(prompt="Enter the number of singular values to use: "))

I presume this is not too dangerous, but this has never really seemed like the
right way to do this. Can someone suggest a better alternative?
