Dear All,
As always, I appreciate all your help.
I would like to know the easiest way to convert each of the homogeneous
elements of a numeric list into a matrix. Each element of this list is also a
list such that when displayed, looks like a 2-by-3 matrix , I would like to
convert each of them into a matrix, without changing the double index of each
entry.
Suppose:
a<- vector("list",2)
> a[[1]]
[,1] [,2] [,3]
[1,] 1 2 0
[2,] 3 4 5
> a[[2]]
[,1] [,2] [,3]
[1,] 5 6 9
[2,] 7 8 10
>is.list(a[[1]])
True
Target: I would like to convert a[[2]] into a matrix, keeping the double index,
into
> mat1
[,1] [,2] [,3]
[1,] 5 6 9
[2,] 7 8 10
The list I have is huge and so is each of its elements, and do not want to use
unlist because I do not understand it fully.
Thank you,
Chee
