Not particularly interested in "points" from you. Would like reproducibility
from you [1], including dput of before and after data, and (inefficient) code
of course.
For loops are part of R.. If your data structure is not set up to take
advantage of vectorization, then for loops are generally
How to apply a function to all elements with the same indices in
multiple arrays? E.g.:
I have two spatial grids defined the same way (i.e., same number of
rows and columns--and dimensions, both 2D). Wherever both
* the value of an element i,j in the first grid is NA
* the value of element i,j i
5 matches
