Hi Simon and Peter
Ouch, I am sorry for raising this.
I hadn't even considered that this basic functionality might only have
entered R between 2.10 and 2.11 - and that trying to use it would not
raise an error pre-2.11.
The Windows PC was that of a student, which is a lame non-excuse for not
trying with 2.11 there.
Sorry again for wasting your time, and best wishes
Wolfgang

Hi,
when running the following on different instances of R (Linux and
Windows), I get different results. The one for Linux seems to be the
intended / documented one. When using numeric indices rather than
characters, Windows seemed to behave as expected.
AFAICT this has nothing to do with the platform but with using an older
R version in Windows that doesn't support it ...
From NEWS:
CHANGES IN R VERSION 2.11.0
[...]
NEW FEATURES
[...]
o n-dimensional arrays with dimension names can now be indexed
by an n-column character matrix. The indices are matched
against the dimension names. NA indices are propagated to the
result. Unmatched values and "" are not allowed and result in
an error.
Cheers,
Simon
