[R] cbind question, please

[Kehl Dániel]

Hello,

I am not sure what you mean by a matrix. If you want to have a matrix, use the function matrix, (matrix(c(dog,cat,tree),3))
but I have the feeling you really want a data frame as you are talking about variables.
In that case simply use 

mydataframe <- data.frame(dog,cat,tree)

If you are not sure what you want, please read the intro to R pdf which is included in your installed R library.

Best regards,
daniel

Tárgy: [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
