hi all,

is there a new mechanism in R 2.3.0 for copying libraries from, say, R 2.2.1 to R 2.3.0? i ask because gabor grothendieck comments in his copydir.bat (from gabor's batchfiles at: http://cran.r-project.org/contrib/extra/batchfiles/batchfiles_0.2-5.zip ):

``::   I personally upgraded my 2.1.0 to 2.2.0 this way so it seems ok until
  ::   R replaces this with something better which is expected for 2.3.0. '''

see also the posting below.

cheers,

thomas.

    Hi Helli, this came up last week, Here are some of the replys posted 
 
1. 
 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). 
 
2. 
 x <- installed.packages()[,1] 
 install.packages(x) 
 
3. 
 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. 
 
4. 
 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)
