Dear Frieda,
I'm afraid that I completely misunderstood your question. I was
unfamiliar with the BiodiversityR package and thought that you were
writing an Rcmdr plug-in for it.
Actually, I see that BiodiversityR uses the Rcmdr interface, but isn't
written as a standard plug-in. Instead, it apparently manipulates the
Rcmdr menu file directly. This is inadvisable, and I suspect that
package is simply incompatible with the current version of the Rcmdr
package. I suggest that you contact the package maintainer, who might
choose to rewrite the package as a plug-in.
Regards,
John

Dear John,
thanks for the quick answer - I'm new to R and sometimes a bit lost
in the
jungle... - version conflict seems to be the problem. I use the
recent
Rcmdr Version but took the plug-in package for BiodiversityR from the
authors page, which seems to be not updated
(http://www.worldagroforestry.org/treesandmarkets/tree_diversity_analysis.asp).
I'll find a working plug-in!
Thanks again
Frieda

Dear Frieda,
I'm afraid that it's not possible to tell from the information that
you've given what the source of the problem is. What version of
Rcmdr
are you using? Have you written an Rcmdr plug-in package for
BiodiversityR? Where in your code is this error produced? Etc.
My guess is that there's a version conflict, since the current
version
of the Rcmdr package on CRAN (1.4-6) doesn't use the variable
operatorFont, which was previously employed to render the various
operator buttons (+, *, etc.) used in the formula fields of
statistical-modeling dialogs. (Now the standard font is used on the
buttons.) This variable was (and is) used nowhere else in the Rcmdr
package. The error was probably produced by the command
getRcmdr(operatorFont); why that should be in your code, I can't
say.
Although I don't know the specific source of the error, I recommend
that you start by updating R, the Rcmdr package, and all other
packages
to their current versions. Your plug-in should call the current
versions of Rcmdr utility functions, such as modelFormula().
I hope this helps,
John

Dear all,
I run R 2.7.2 under Windows and integrated BiodiversityR
sucessfully
into
the R commander. Most functions of BiodiversityR run but others
(like
analysis of species as response) produce blank windows and the
message:
Error in get(x, envir = RcmdrEnv(), mode = mode, inherits = FALSE)
:
Variable operatorFont nicht gefunden
What's wrong?
Best regards, Frieda
