Not sure what would be desirable here? matrix(1,1,1)?

Note that the following works:

> perm_matrix(as.word(1:5))
     [,1] [,2] [,3] [,4] [,5]
[1,]    1    0    0    0    0
[2,]    0    1    0    0    0
[3,]    0    0    1    0    0
[4,]    0    0    0    1    0
[5,]    0    0    0    0    1

current behaviour different:

> perm_matrix(id)
Error in dimnames(x) <- dn : 
  length of 'dimnames' [1] not equal to array extent

Back again:

> id
[1] ()
> perm_matrix(id)
<0 x 0 matrix>
