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

Is this what you're looking for?
dog - 1:3
bat - 2:4
tree - 5:7
big.char - c(dog,bat,tree)
do.call(cbind,lapply(big.char, get))
[,1] [,2] [,3]
[1,]125
[2,]236
[3,]347

Here is the big picture. I have a character vector with all of the

I want to cbind all of the variables to create a matrix.
Doing 3 is straightforward, but many, not
I am amazed at the number of rather obtuse misunderstandings of the
actual nature of Erin's question.
The suggestion that Erin should read the intro to R made me smile. Erin
is a long time and highly sophisticated user of R; she has no need to
read the intro. The person who made that
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 25
[2,] 2 36
[3,] 3 47
But I can't imagine that is the solution
You could do something tricky like
do.call(cbind, lapply(big.char, as.name))
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
but you are usually better off creating these things as part of a list
and passing that to do.call(cbind, list).
There is a slight danger
Perhaps:
dog - 1:3
cat - 2:4
tree - 5:7
big.char - cbind(dog,cat,tree)
big.char
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
colnames(big.char)-c(dog,cat,tree)
big.char
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47

Hi Erin,
Well, if I do this:
dog - 1:3
cat - 2:4
tree - 5:7
dct-cbind(dog,cat,tree)
I get this:
dct
dog cat tree
[1,] 1 25
[2,] 2 36
[3,] 3 47
If I assume that you want to include the character vector as well:
rownames(dct)-big.char
dct

This is a toy example. There will be a bunch of variables.
