unable to change dim about delayedarray

[hpages]

Ah, perfect! DelayedArray objects didn't support this so far and I was thinking in adding it. It's on the TODO list:

DelayedArray/TODO

Lines 14 to 16 in 998fa6a

	- dim() setter allows dropping ineffective dimensions so should also allow
	adding ineffective dimensions e.g. if dim(A) is c(2, 10, 8) we should be
	able to do dim(A) <- c(1, 1, 2, 10, 1, 8).

I think it should be easy. Great that you have a use case. I'll try to have this ready today or tomorrow.

Great!

This should work with DelayedArray 0.7.42: b8a6103

Note that, unlike with an ordinary array, the are still restrictions w.r.t. what the dim() setter can do on a DelayedArray object x. For example if dim(x) is c(5, 4), you can't do dim(x) <- c(10, 2). However you can change the order of the dims with aperm() (generalized transposition).

Nice! Thanks a lot.
