I may not understand things, but what I do with my home-brew package in
Windows is this:
First detach the current package - Type detach("package:your.package")
<enter>
Next, click on Packages, Install package(s) from local zip files, and click
on the updated zip file.
Finally, click on Packages, Load package ... , and click on your.new.package
in the drop-down menu.

Subject: [R] unload & reload a (new version of a) package
i'm putting the final touches on a package that i'm developing and i
noticed
that if i detach the package, and then re-build & re-install it (using R
CMD)
then I can't get the newer version of the package to load in the
existing R
session (i have to close it out and start a new session, then the newer
version of the package is loaded).
looking through the source of 'detach' i see :
.Call("R_lazyLoadDBflush", paste(libpath, "/R/", pkgname,
".rdb", sep = ""), PACKAGE = "base")
is there some absolute way similar to the above to flush the package db
and ensure that a newer version of the package can be loaded into the
existing R session? detach calls .Last.lib and seems to go through the
motions of purging the loaded package; why, then, is the package still
lurking around in the existing R session?
it's not a big deal; it's only a minor pain having to re-start an R
session.
i'm more interesting in why this is happening.
cheers,
thomas.
