Re: [R] matrix loop

What exactly are you intending the loop to do? Why do you have the 'as.matrix' in the middle of the loop? Where was 'y' defined? Does this do what you want?

> outer(1:5, 1:10, "+")

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]

```[1,]    2    3    4    5    6    7    8    9   10    11
[2,]    3    4    5    6    7    8    9   10   11    12
[3,]    4    5    6    7    8    9   10   11   12    13
[4,]    5    6    7    8    9   10   11   12   13    14
[5,]    6    7    8    9   10   11   12   13   14    15

```
