Re: [R] How to updating R to the newest version conveniently
On what OS? If Windows, this is covered in the rw-FAQ. If other, it depends on how you install R (from sources, RPMs, etc). On Thu, 11 Nov 2004, Yong Wang wrote: > I have been using R for a while.

RE: [R] How to updating R to the newest version conveniently
I've seen various answers to this question and there does not seem to be a
single best way.
I use a separate library for downloaded packages. In windows I set the R_LIBS
environment variable. See the usual suspects such as the appropriate FAQ and
the r-admin pdf file. On the exisitng installation I run code like this
myPackages <- .packages(all.available = TRUE,lib.loc = "c:/progs/mylib")
save(myPackages,file = "f:\backup\settings\myPackages.rdata",compress = T)
This stores a list of all the packages in "mylib" so that when a new install
comes I can just retrieve my backup and do a new install. When everything is
working well a new version can be downloaded in the old directory (having
cleaned it out first) and the update from CRAN option in windows can be used.
However with R2.0 there was a need to recompile packages so those that did not
have a new version did not update, but didn't work with the new version.
load("f:\backup\settings\myPackages.rdata")
install.packages(myPackages,lib = "c:/progs/mylib",
"CRAN = http://cran.au.r-project.org/";)
I can't guarantee the code as I have just put it together from what I recall
(this is how I did it at home) I don't have that sort of access to the work PC
so I have to get a tech support person to do it all for me and they have to do
it manually because they don't understand the process.
Ciao, Tom

Subject: [R] How to updating R to the newest version conveniently
Dear R users
I have been using R for a while. However, I don't know what is the
convenient way to update R to the newest version while keep all packages
I previously downloaded and installed from CRAN, if updating all those
packages the same will be even better.
for the time being, I reinstall all those package evrytime after updating
the version.
Thank you.
best regards
yong
