Dear all,
In my gRbase package I have up until now "Depend"-ed on RBGL (from Bioconductor), but
good people have convinced me that I should use "Import"-it instead because I only use
few functions from RBGL.
In DESCRIPTION I therefore now have
Imports: Matrix,RBGL
In NAMESPACE I now have
importFrom(RBGL, maxClique, is.triangulated, separates)
The package compiles without complaints, but I have noticed that if I start a fresh
R-session, then maxClique etc. from RBGL is NOT available for "interactive use"
in my session:
library(gRbase)
maxClique
Error: object 'maxClique' not found
1) Is this as it should be?
2) If yes, is there any other way in which maxClique can be imported for
interactive use without Depend-ing the whole RBGL package?
The importFrom directive effectively makes local copies of those
functions in your package (with the usual caveats that copies aren't as
inefficient as you might think). If you want to export them, you need
to add them to the exports list.
