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.

Best,

Thanks!
