Actually, this did not work (on multiple architectures from 2.15.2 to
3.0.0 as well as from 3.0.0 to 3.0.1) for me in the sense that it only
offered to update a very small subset packages, and that too, without
their dependencies. Which resulted in a failure also for a large subset
of the small subset of packages.

As an example, consider the following:

> update.packages(checkBuilt = TRUE)
> 

(nothing to update, since I updated some things yesterday, and did a
manual installation when the dependencies, eg lme4 comes to mind,
failed)

> installed.packages()[,"Built"]

shows that AnalyzeFMRI was Built for 3.0.0.

Perhaps not a big deal from 3.0.0 to 3.0.1 but was a big deal from
2.15.2 to 3.0.0.

But after doing a 

? install.packages("AnalyzeFMRI")

I get that 

AnalyzeFMRI is Built for 3.0.1.

Trying:

> install.packages(installed.packages()[,1])

I get that all are updated to 3.0.1, except for some, like XLConnectJars
which are not available.

(I was surprised: it may be a bug, but is definitely a desirable
feature that should be considered for inclusion.)

Perhaps the better thing to do would have been to:

> update.packages(installed.packages()[,1])

but I did not think about that earlier.

Many thanks and best wishes,
Ranjan
