That it worked with 1.4.3 is suspicious, sure. But I think the help text should be fixed first.

Sure, the help text could be better, absolutely :-)
I do agree with the inconsistency you mentioned => confirmed.

I myself wouldn't have plugged those inputs directly into anovan, I'd see them more as a guide on what kind of inputs are expected. Hmmm, I guess I became quite a bit wary after 45+ years of reading IT-related manuals, that's probably why a took a different stand initially. But you're really right.

The anovan demos look pretty complex; a few simple examples in the help text that actually work could overcome a steep learning curve.

Would you have a suggestion for an example that can replace that help text stanza?

The help text has

------
P = anovan (Y, GROUP)
...
For example, if ‘Y = [1.1;1.2]; GROUP = [1,2,1; 1,5,2];’ then observation 1.1 was measured under conditions 1,2,1 and observation 1.2 was measured under conditions 1,5,2.
------

and it means to me that one can plug in Y and GROUP as mentioned without getting an error. My original example was slightly modified. Note also that it works with package version 1.4.3.

To me it looks like the OP didn't understand the help text. I don't see any call 'anovan ([1.1;1.2], [1,2; 1,2])' mentioned there.
IMO the part of the help text where the input args Y and GROUP are treated just indicates what the Y and GROUP input arguments do.
Possibly the help text can be a bit more clear.

cc'ing package maintainer anyway

the simple example (from the help text)

anovan ([1.1;1.2], [1,2; 1,2])

throws the error

error: cat: dimension mismatch
error: called from
    cell2mat at line 86 column 11
    anovan at line 617 column 36
