[BioC] Examples outdated in "Bioinformatics and Computational Biology Solutions Using R and Bioconductor"

[Heidi Dvinge]

Hello Peng,

please keep discussions to the list, so that other people can chime in as
well.

I'm not familiar with the details of xtable, but in the example you link
to below it seems like the function xtable.matrix() does exist, but it's
not exported by the name space. However, simply using xtable() works fine
for me, and gives the same result at calling xtable.matrix() specifically
(code shown below).

There might be an updated version of the examples from "Bioinformatics and
Computational Biology Solutions Using R and Bioconductor" somewhere;
someone else can probably tell you. My best advice though is, that when
something doesn't work, simply do a search for that function/package ;)
Typing ?xtable.matrix gives you the xtable help page, which a.o. says "The
available method functions for xtable are given by methods(xtable)."

Regards
\Heidi
