Hi,

I have a further question about matrix manipulation.

Imagine the following two matrices:

> test

[,1] [,2] [,3] [,4]

*[1,] 1 0 6 4
**[2,] 2 5 7 5
*

[3,] 3 6 8 6

[4,] 4 0 0 0

> matrix(is.element(test,0), ncol=4)

[,1] [,2] [,3] [,4]

*[1,] FALSE TRUE FALSE FALSE
**[2,] FALSE FALSE FALSE FALSE
***[3,] FALSE FALSE FALSE FALSE
**

So after applying the TRUE FALSE matrix the test matrix shoud look like the following:

[,1] [,2] [,3] [,4]

[1,] 2 5 7 5

[2,] 3 6 8 6

Cheers
