Reading labels for very large heatmaps
Hello,
I have a large (919 X 919), hierarchically clustered heatmap that I would
like to read the labels off of. I have tried saving the figure in pdf
format and enlarging it until I can see the labels, but if I make the labels
small enough to read (so that they don't overlap) using cexRow and cexCol,
they do not appear in the pdf. The limit seems to be anything below cexRow
or Col = 0.06. Is there a way to have smaller labels visible in the pdf?
Is this an issue with resolution? I could get by with just a quarter of the
heatmap (i.e. half of a row and half of a column) so that t...

Change font type for rows on Heatmap
Hi,
I would like to change the font type (to courier) of my rows labels when
I plot a heatmap with R.
I have used cexRow=0.7 to modify the size but didn't find anything
regarding font type.
heatmap(as.matrix(cebpa50), margins=c(5,10) , Colv=NA , scale="column",
col=col4, cexRow=0.7)
Thanks,
Ben

Row labels are skewed in 'heatmap' (PR#7358)
...on 1.8.1
OS: Irix64
Submission from: (NULL) (130.225.67.236)
I've made a script look like this:
exp <- read.table("graph/1933672048.cluster.data")
exp <- as.matrix(exp)
postscript("graph/1933672048.cluster.data.ps")
heatmap(exp,scale="none",cexCol=0.4,cexRow=0.2,col=custom,margins=c(5,5))
The row labels on the output PostScript file are skewed vertically downwards -
in fact more than the height of 2 rows! I have roughly 200 rows and 4 columns in
my dataset. It is therefor very difficult to see which label goes to which row

heatmap clustering dendrogram export

I am a beginner for R.

It work well. It generate heatmap whith rcolumn clustering dendrogram and I
can export a very nice graph. But I don not know how to export the column
clustering dendrogram out. Because I want to get the dendrogram for next
step analysis. If I can export it as the newick format (or...

...s and spend several
hours with trial and

It's all about lines in a heatmap to separate different data block from
each other to underline
the significance of the found clusters!
The heatmap is build like that:
heatmap(X, Rowv=NA, Colv=NA, symm=TRUE, cexRow=0.3, cexCol=0.3)
I switched the dendrograms off, because I don't want the values sorted
but in the way, I
extracted them from the data.
I tried to enter the lines that way:
lines(c(14,14),c(0,187), col="green")
That should appear as a line parallel to the x-axis, but there was no...

heatmap.2 - change column & row locations; angle / rotate
Hi Chakravarthy,
[dont forget to Cc the list for useRs with the same Q.]
If you're trying to reuduce the isze of your row or column labels, i
think the following arguments of heatmap.2 {gplots} is what you want to
adjust- 'cexCol' and 'cexRow'.
Specifically on my question that you ask about, i found the BioC forum
helpful:
http://permalink.gmane.org/gmane.science.biology.informatics.conductor/30112
And in fact the phylotemp() function by default pretty much did exactly
what i needed, available here:
