Ups, but this is a bug, isn't it?  Why is this black hardcoded?

I could try this for the moment - but where can I report this as a bug?

Kind regards

Unfortunately this does not work.  I even tried to rename "legend" to
"mylegend" to make sure that my changed version is really used. If I
do so I get

    Error: could not find function "mylegend"

which explains why the changed function legend seems not to be used -
the function definition just pasted in the R script before I call the
legend function is ignored.

Despite the fact that this does not work I'm looking for a simple way
to put the new definition in an extra file that is just included by
my R - scripts (I have more than one).  I'm thinking of a similar thing
like "\input" for TeX or "#include" for C or something like
that to store
the hack in a separate file.

Kind regards

          Andreas.
