I've been trying to create a heatmap of an RNAseq experiment. I've followed the following online tutorial:

However, when I get to creating the heatmap steps:

geneids <- c(up_gene_data$gene_id)
myGenes <- getGenes(cuff_data, geneids)
csHeatmap(myGenes, cluster="both")

I get this error message:

> csHeatmap(myGenes, cluster="both")
Using tracking_id, sample_name as id variables
No id variables; using all as measure variables

and I produce a PDF that is not a proper heatmap. The names of the genes are squished to the right side.

Ive followed suggestions from the following post: Heatmaps from cuffdiff output . However, I am still not getting a proper heatmap.

I also wanted to know if I should also install separately the following packages as recommended in the cummeRbund manual:

RSDLite, ggplot2 v0.9.2, reshape2, plyr, fastcluster, rtracklayer, Gviz and Hmisc.
