The byte code attached to each function in a package can be surprisingly

Matrix:::replTmat seems to be c. 4.5 times the size of the raw code:

object.size(as.function(as.list(Matrix:::replTmat)))
5.5 bytes
[Is there a more direct way to remove byte code from a function? Or to
inspect it?]
You can sort of inspect it using compiler::disassemble, though it's not
very readable. You can remove it by assigning to the body, e.g.
body(fn) <- body(fn)

Building Matrix with --no-byte-compile reduces the size of R/Matrix.rdx
by more than half, from 2.7 MB to 1 MB.

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.
