Have you tried P2["20", "10", "0"] ?

Hi all,
I have a three dimensional array with the corresponding dimension names.
I would like to subset the array according to the dimension names. For
example,
suppose I want to extract the values corresponding to A=20, B=10, C=0. I
know I
can do:
P2[dimnames(P2)$A==20, dimnames(P2)$B==10, dimnames(P2)$C==0]
But is there a better way for doing this? Thanks for your help!

$A
[1] "20" "25" "30" "35" "40"
$B
[1] "5" "10" "15" "20" "25" "30" "35" "40"
$C
[1] "0" "5" "10" "15" "20" "25" "30" "35"
