[R] cannot assign dimnames

[Jan Goebel]

Dear Dan,

a simple example:

> mat<-matrix(1:6, ncol=3)
> mat
     [,1] [,2] [,3]
[1,]    1    3    5
[2,]    2    4    6
> dimnames(mat)<-list(1:2, 1:3)
> mat
  1 2 3
1 1 3 5
2 2 4 6
> dimnames(mat)<-list(1:2, letters[1:3])
> mat
  a b c
1 1 3 5
2 2 4 6
> dimnames(mat)
[[1]]
[1] "1" "2"

[[2]]
[1] "a" "b" "c"

dimnames need a list!
