Hello Erin,

I think you have explain your goal more detailed. Maybe I am completely lost but as far as I understand now you only need the command cbind:

m1 <- cbind(dog, dat, tree)

 dog cat tree
[1,]   1   2    5
[2,]   2   3    6
[3,]   3   4    7

But I can't imagine that is the solution you are looking for.

Cheers
David

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
