> NULL * matrix(1:4, 2) Error: dim<- length of dims do not match the length of object
The equivalent of the NULL was a variable that was meant to be a scalar. It took me a while to track down the problem because I was focusing on looking for arrays that were different than my expectation.
I think it could save substantial debugging time if the error message stated the dims and the length of the object.
Also with
options(error=dump.frames)
set before the command above, we get:
> debugger() Message: Error: dim<- length of dims do not match the length of object Available environments had calls: 1: 0:
Enter an environment number, or 0 to exit Selection: 1 Selection: 0 >
That is, there is apparently an environment to select, but trying to select it doesn't do anything.
This is with R version 1.8.1 on Windows and SuSe 8.2 (both precompiled).
