Just out of idle curiosity I tried this.  (Don't want/need XML, but since
I've fairly recently started using Ubuntu, I like to see whether I can drive
these sudo apt-get tools .....)

So I did

     sudo apt-get install r-cran-xml

and it seemed to run without error.  Then I started R and tried

     library(XML)

and got the error

     Error in library(XML) : there is no package called 'XML'

So I then said ``Hmmmm.  Maybe I've misunderstood, and the sudo apt-get 
bizzo
has just provided the underlying xml2-config stuff, and I still need to 
do the install
of the R package XML.  So I tried that, and got the message:

     checking for xml2-config... no
     Cannot find xml2-config
     ERROR: configuration failed for package ‘XML’
     * removing ‘/home/rolf/Rlib/XML’

So either something's not working properly or I'm still not 
understanding what
I should be doing.  Enlightenment?

     cheers,

P. S. I *believe* that I have the Ubuntu repositories referenced 
correctly in
my /etc/apt/sources.list file:

deb http://cran.stat.auckland.ac.nz/bin/linux/ubuntu lucid/
