Hi John,
I suspect you may be missing a c()?

You can use the command library() to get a list of what is installed on your
machine.
Is it possible to get this as a vector of only the package names, or
is post-processing the output of library() the only way out?
Do you mean something like:
paks = library()$results[,1]
save(paks, file = 'paks.RData')
Rob
Exactly! Then
install.packages(library()$results[,1])
does all the updated installs in one shot.
Why do you want to reinstall all packages?
I'd go for
udpate.packages(checkBuilt=TRUE)
if a reinstallation after an update of R is what you are aiming at.
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
Right, it won't reinstall here since that is not necessary and the
package sources were not changed, hence it safes you time and bandwidth.
but was a big deal from
2.15.2 to 3.0.0.
Right, and it would have updated there....
But after doing a
? install.packages("AnalyzeFMRI")
I get that
AnalyzeFMRI is Built for 3.0.1.
Yes, sure.
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.
This is not a CRAN package and binaries may not be available in the
repository you tried to get it from (Omegahat) or you have not selected
Omegahat as a repository via setRepositories().
You can try to install from sources, though.
As I said before, replacing all your packages unconditionally wastes
bandwidth. There are rarely situations where the other updates are
really needed.
Best,
Uwe Ligges
(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
Best,
Uwe Ligges
Thanks!
