In general the cbind function is used to bind columns into an array.
If you want to invoke it on a list of arguments you can use do.call to
create the function call.  Combining these gives

> mylist <- list(c(1,2,3),c(4,5,6)) 
> do.call("cbind", mylist)
     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6
