Hi All,
This is not a Bioconductor question per se, but I was wondering if
people have used the heatmap() function to create heatmaps of gene
expression data. I would like to put a color key indicating changes in
expression, but there is no apparent argument for "key".
Alternatively, I believe that the gplots package contains an enhanced
heatmap generator (heatmap.2) which does allow color keys to be made,
but after downloading gplots, I tried to load the package and got the
following:
trying URL 'http://stat.ethz.ch/CRAN/bin/macosx/leopard/contrib/2.12/g
plots_2.8.0.tgz'
Content type 'application/x-tar' length 332781 bytes (324 Kb)
opened URL
==================================================
downloaded 324 Kb
The downloaded packages are in
/var/folders/Mg/Mgbv9bdKEqykYZ+cmG5adE+++TI/-Tmp-//RtmprvL7Vp/download
ed_packages
Loading required package: gtools
Error: package 'gtools' could not be loaded
In addition: Warning message:
In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc
= lib.loc) :
there is no package called 'gtools'
Has anyone seen this problem before? If someone has an alternative
method for generating a heat map from a .csv file, I'd love to know.
Thanks,
Shaun
