cbind question, please

This works for me...

get0 = function(x) get(x,pos=1)
sapply(big.char, get0)

The extra step seems necessary because without it, get() gets base::cat() instead of cat.

cheers,
    Steve

Subject: [R] cbind question, please

Hello!

I have a cbind type question, please:  Suppose I have the following:

dog <- 1:3
cat <- 2:4
tree <- 5:7

and a character vector
big.char <- c("dog","cat","tree")

I want to end up with a matrix that is a "cbind" of dog, cat, and tree.
This is a toy example.  There will be a bunch of variables.

I experimented with "do.call", but all I got was
1
2
3

Any suggestions would be much appreciated.  I still think that do.call
might be the key, but I'm not sure.

R Version 3-1.3, Windows 7.

Thanks,
Erin
