A minor inconvenience in updating an R installation is remembering which packages were installed previously. Has anyone written a script to inspect a previous installation, then get & install the same packages into the new installation?

In http://cran.r-project.org/contrib/extra/batchfiles/batchfiles_0.2-5.zip are two Windows XP batch files: movedir.bat copydir.bat which will move the packages (which is much faster and suitable if you don't need the old version of R any more) or copy the packages (which takes longer but preserves the old version).

x <- installed.packages()[,1] install.packages(x) Uwe Ligges
This is one reason we normally recommend that you install into a separate library. Then update.packages(checkBuilt = TRUE) is all that is needed. However,
foo <- installed.packages() as.vector(foo[is.na(foo[, "Priority"]), 1])
will give you a character vector which you can feed to install.packages(), so it's not complex to do manually.

If the previous installation is still alive, fire it up and
pS <- packageStatus()
pkgs <- pS$inst$Package[!pS$inst$Priority %in% c("base", "recommended")]
save(pkgs, file = "foo")
In the new installation,
load("foo")
install.packages(pkgs)
