[R-pkg-devel] What influences the size of the rdb file in a package

[Mosqueira Sanchez, Iago]

As far as I can see only classes, methods and functions are present
there. I loaded the rdb file and looked at the contents and sizes of
objects.

Am I right in assuming every method or function imported from another
package sits in the database? In another S4 package I see that the
largest objects are nls, cor and lm, which we overload for some S4
classes.
