Hi,
I am trying to get the positions in array coordinates (needed later) of certain
elements in an array but I am not sure how to get them.
My array is Q and the condition is dt>dV, where dt and dV are arrays of exactly
the same dimensions as Q.
I know that I can extract the elements of Q by using Q[dt>dV] but I need the
array position of where this happens.
I don't see how to use the which() command since some elements given by that
the condition are not unique
( I tried which(Q==Q[dt>dV] ,arr.ind=TRUE) but that gives me too many positions
plus
Warning message:
In Q == Q[dt > dV] :
longer object length is not a multiple of shorter object length)
Any help would be really appreciated!
