[BioC] Upgrading R

[Sim, Fraser]

It's very simple to maintain a small .R script file which runs a
combination of biocLite and install.packages(). You can have all the new
packages installed in about 30-60 mins on a typical connection. 

I've done this for a number of installs and it is very efficient.

Hi Chintanu

I have struggled with this problem through several upgrades and I have
not found a consensus of the best way to do it. There are quite a lot of
suggestions and advice if you search around using RSiteSearch().

I think the most straightforward answer I have found is described here:

http://batchfiles.googlecode.com/svn/trunk/README

I have not investigated fully - perhaps copydir is the way to go?

But my last upgrade I used this:

Look for the README and the part that describes the alternative to
copydir:


"An alternative to copydir is to reinstall all packages

	# Alternative to copydir.bat #1
	# this example is for moving from 2.4.1 to 2.5.0
	# run this in R 2.5.0
	setwd(R.home())
	ip <- installed.packages(lib.loc = "../R-2.4.1/library")
	ip <- ip[ip[,1]!="base" ,1]
	install.packages(ip)

"


I hope this helps.


Regards

John Seers

Hi,
Wonder if there is a way to upgrade R.
I'm currently using R 2.7.2, and wish to 'upgrade' to the latest one via
some process that doesn't make me reinstall all the packages again !!
Please let me know.
Thank you !
Chintanu
