R devel - Jul 2005 - Spurious output like <environment: namespace:base> in R-devel

I have noticed spurious message of the form
<environment: namespace:base>
when developing code for the Matrix package and testing under R-devel.
 These messages are not present when testing under R-2.1.1

I have not reported this because I didn't know if it was caused by my
code in the Matrix package or some other code.  Today I checked the
newly uploaded vcd package under R-devel and got the same symptoms.

Try

library('vcd')
example(mosaic')

to reproduce the problem.  If you want to see the same problem in the
Matrix package run

R-devel CMD check Matrix

and look at the output in Matrix.Rcheck/tests/lmer.Rout

Thanks Duncan.  In my code it turns out that the two .Call calls that
were producing the spurious output did not have PACKAGE = "Matrix".
Once I fixed that I no longer got the spurious output.
