The message is from maptools (as it says), not sp.
Thank you very much prof. Ripley for pointing out my error.
No, there is nothing you can do when dependent packages put out
messages. You could ask the maintainer not to put the message out when
rgeos is available ....
I'll try.
All the best,
Mauricio

Dear List,
I'm building a package that uses 2 functions of the 'sp' package, and
I declared them in my NAMESPACE file as follow:
importFrom("sp", proj4string, coordinates)
The package is built without any problem, but when I load the package,
I get the following message:
"
Loading required package: sp
Note: polygon geometry computations in maptools
depend on the package gpclib, which has a
restricted licence. It is disabled by default;
to enable gpclib, type gpclibPermit()
Checking rgeos availability as gpclib substitute:
TRUE
"
However, if I only load the 'sp' package (in a different R session), I
don't get any warning message.
Is there any way I can prevent the warning message appears when I load
my package ?
Thanks in advance for any help,
Mauricio Zambrano-Bigiairni
