[R] Putting an index explicitly into function code --- a curiosity.

I want to create a list of functions in a for loop, with the index of the loop appearing explicitly in the function code. After quite a bit of thrashing around I figured out how to do it. Here is a toy example: junk - vector(list,4) for(i in 1:4) { itmp - i junk[[i]] -

Re: [R] Putting an index explicitly into function code --- a curiosity.

I imagine the answer will involve lazy evaluation and require you use force() but I'm not quite qualified to pronounce and not at a computer to test. Michael On Jan 6, 2012, at 8:43 PM, Rolf Turner rolf.tur...@xtra.co.nz wrote: I want to create a list of functions in a for loop, with the

Re: [R] Putting an index explicitly into function code --- a curiosity.

Presumably because the i = 4 has to be re-evaluated at the start of each iteration of the while-loop which implicitly force()s it? Though, I don't know if it might not be a bad idea to put an implicit force() in the internal code for `for` to prevent these sorts of things. I can't immediately
