Thank you for the report.

yes.
You are using "T" and "F" in your package instead of "TRUE" and "FALSE".
This is now tested a bit (by setting T <- F <- NULL).

NEWS of "R-1.6.0 beta" 
----		       (probably should be read by ``everyone'')	
has

||     o	R CMD check now tests for mis-use on an installed or binary
|| 	package, and sets 'T' and 'F' to 'NULL' when running the examples.

where I'm pretty sure you won't be the only one..

BTW, (not to Göran, but the publich), also in NEWS

||    o	The assignment operator `_' is deprecated: a warning is	given
||	once per R session.

which really suggests to everyone (you should finally listen ;-) ..
your R code might no longer run in the not so distant future (some time
next year probably) when you'll still be using "_" for assignment
