dimnames and subscripting (PR#293)
Fri, 8 Oct 1999 10:43:53 +0200 (MET DST)
I am not sure that this is a bug, but it was unexpected -- of course my
expectations are fallible, eg column ordering in model.matrix()! When an
array is subscripted the names of the dimnames list are lost (v 64.1).
fred <- array(1:12, 2:4, list(A = letters[1:2], B = letters[3:5], C =
dimnames(fred[1, , ])
dimnames(fred[1, , , drop=FALSE])
In the first case I expected names B and C to be preserved; in the second
case, not quite so clear-cut, I also expected B and C to be preserved.
