[R] how to collapse a list of 1 column matrix to a matrix?

[adschai at optonline.net]

Hi, 

I encounter a situation where I have a list whose element is a column matrix. Says, 

$'1'
[,1]
1
2
3

$'2'
[,1]
4
5
6

Is there fast way to collapse the list into a matrix like a cbind operation in this case? Meaning, the result should be a matrix that looks like:

      [,1]  [,2]
[1,]    1      4
[2,]    2      5
[3,]    3      6

I can loop through all elements and do cbind manually. But I think there must be a simpler way that I don't know. Thank you.
