Hi Nick,

I'm putting rkward-devel back on CC. Hope that's ok with you.

(Background: I had to resend my previous message privately, due to problems 
with an over-active spam-filter along the way).

This should not be an issue, right? (It does look like a good idea to remove 
the argument name, though, as, sometimes, R does rename first arguments 
(perhaps to "packages" in this case), while they rarely touch argument 
position. So I stripped the "pkgs=" in the development version).

>  2), suggested_packages=TRUE

Ouch. Search-and-replace bug, now fixed in the development version.

Note: If you would like to test the fixes, compiling the development version 
is just as easy as compiling from the official tar.gz releases. See 
http://p.sf.net/rkward/svn .

True, it uses only "@CRAN@" and "http://rkward.sf.net/R" by default. This is 
not an entirely clear-cut-case, but actually, this is done on purpose. Note 
that you can manage repositories via the "Configure Repositories"-button in 
the package installation dialog (also available via Settings->Configure 
RKWard).

No, the option really controls installation of "suggested" packages, only (and 
thus, to work around the error, I suggest simply leaving it unchecked). Note 
that the "dependencies"-parameter to install.packages() allows for much more 
fine-grained control. But the difference between dependencies=TRUE and 
dependencies=NA is the "suggested" packages, only. Actual dependencies are 
installed in both cases.

See above on the name of the "dependencies" argument in R. Thanks for 
reporting!

In general, installing "all updates" should fix this. However, in fact, we 
should probably adopt the R way of dealing with this: Keeping separate library 
locations for different versions of R. The downside of this is that after 
every new (non-patch) version of R, you will have to re-install all packages, 
while most of the time this would not actually be necessary. The advantage is 
that you will never run into this problem.

To do it the R way, manually, remove/rename ~/.rkward/library

Well, thanks for your feedback. Keep reporting issues!
