heatmap.2 no reordering of the columns and rows
Hi,
  I need to generate a heatmap on a square matrix and wouldn't want to reorder the columns and the rows on the heatmap display.  
  I have used the options Rowv=NULL and Colv=NULL but doesn't seem to work. Following is a snippet of the heatmap function i am using.
args <- commandArgs();
inputfile <- args[2]

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.

heatmap clustering dendrogram export
Hi,
I am a beginner for R.
I had use gplots to generate a heatmap as following:
>heatmap.2(matrix, col=topo.colors(75), dendrogram="column", Rowv=FALSE,
trace="none", key=TRUE, keysize=0.8, density.info="none", cexRow=0.2,
cexCol=0.6)
It work well. It generate heatmap whith rcolumn clustering dendrogram and I
can export a very nice graph. But I don not know how

lines() in heatmap()
Hello!
I looked for help through google and the help-files 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:

problem formatting and positioning title in heatmap
I am using heatmap with the arguments below. The title size stays the 
same no matter what I set cex.main to. Is this expected? Can I adjust 
the title size in heatmap?
Also, the position of the main title is at the very upper edge of the 
output and if I use a "\n" to stack the title the upper line is out of 
bounds and doesn't show up.
I am outputting to pdf.
Any help? Thanks,

heatmap2 error key
Hi I am trying to understand what happen with the heatmap.2 code that it
used to work (last used in October 2015). I am able to get a heatmap but my
colour key doesn't come up and instead I get an error in all my files the
used to work. Does anyone has any idea of what could have changed? or how
to fix this.
Thanks.

Correlation Mapping
On the cover of Zivot and Wang's Modeling Financial Time Series with S
Plus, there is a correlation plot that seems to indicate the strength
of correlation with color-coded squares, so that more highly
correlated stocks appear darker red.  If anybody out there is familiar
with the book or understands what I am talking about, I am curious as
to whether or not there is a similar function in R

problem with heatmap.2 in package gplots generating non-finite breaks
I have written a wrapper for heatmap.2 called
heatmap.w.row.and.col.clust which auto-generates breaks using
breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20,
digits = 2)  #(stddev in this case = 2.5)
This has always worked well in the past but now I am getting an error
that non-finite breaks are being generated. Drilling down, it seems
that my wrapper is generating finite

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.

Improving on Rice coding
Hello,
I am the author of the Bonk audio compression program... i've just been
looking at your comparrison table, and i noticed bonk gets marginally
better compression than Flac on some files (actually i was
rather surprised to see bonk on the list at all, it's not exactly high
profile :-) ).
Bonk in lossless mode is a pretty naive implementation of a predictive
coder, so the main

listening experiment
Hi All,
I was wondering whether there have been some listening experiments done 
to test how well spatial information is preserved in the celt signal, 
e.g. comparison of sound localization performance for the original 
uncompressed sound and the celt sound (most probably for different bit 
rates).
Best, Pablo

really irregular time series
I built some reasonably successful tools in a graphical database for
reconstructing the developmental turning points for feedback loop driven
natural processes.    I'm trying to move it to R and am having
difficulty with the very basics, i.e. a) defining time series using time
as a natural number rather than a place in a table.    I was also hoping

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

labRow/labCol options in heatmap()
The function heatmap() allows to specify row/column labels
via the options labRow/labCol. From the code of heatmap(),
I understand that when no labels are specified, the row/column
labels (or indices) of the input matrix are taken as labels and 
re-ordered together with the rows and columns of the matrix before 
plotting, whereas labels supplied via labRow/labCol are plotted
in the original order.
