Odp: accessing dimension names
Hi r-help-bounces at r-project.org napsal dne 18.12.2007 12:01:41:
I have a matrix y:
dimnames(y)
$x93 [1] "1" "2" $x94 [1] "0" "1" "2" .................. so on (there are other dimensions as well) I need to access a particular dimension, but a random mechanism tells me which dimension it would. So, sometimes I might need to access dimnames(y)$x93, some other time it would be dimnames(y)$x94.. and so
on.
Now let that random dimension be idx, then
dimnames(y)$paste('x',idx,sep='')
doesn't work.
Why not dimnames(y)[idx] Regards Petr
Can anyone help? Thanks! [[alternative HTML version deleted]]
