par(mfrow) for heatmap plots
Hi,
I was trying to use par(mfrow) to put 4 heatmaps on a single page. However,
I get one plot per page and not one page with 4 plots. What should I
modify? Test code is given below:
test = matrix(rnorm(60), 20, 3)
pdf(file='test.pdf',width=10,height=8)
par(mfrow=c(2,2))
heatmap(test)
heatmap(test)
heatmap(test)
heatmap(test)
dev.off()
thanks!

par(mfrow) for heatmap plots
The answer is "don't do that" because that function abuses par. Use lattice or ggplot2 with grid graphics to plot multiple heatmaps.

comparing heatmaps
Dear all,
I've been trying to find how to compare tow different heatmaps but I'm having trouble getting the colors bar to be the same. I'm doing something like the following:
library(gplots)
dat<-cor(matrix(rnorm(100, m=10), nrow=10))
mat<-cor(matrix(rnorm(100), nrow=10))
dev.new()

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.

Saving heatmaps as PDFs
Hi,
I'm trying to save heatmaps as PDFs. However, the PDF version of the
heatmaps (Heatmap_CAFvsTNF_run2.pdf) is blurred when compared to its
counterpart, which was saved manually by using the software
"Grab" (Heatmap_CAFvsTNF_run2.tiff).

vertically oriented color key in heatmaps
Hi, I have some data which I was plotting using image(). I wanted to
add a vertical color key to the plot and I found that heatmap.2 in
gplots does let me add a color key. However, I was thinking of a
vertical bar with the color range rather than the style that gplots
provides.
Is there any package (or code snippet) that would let me add a
vertical color key to an image() or heatmap

Making heatmaps
Basically, I have the location data for about 1,000 pitches. I can get them
to show up correctly on normal plots, but I am genuinely messed up on
heatmaps.
> location <- read.csv('C:/Users/William/Downloads/09Location.csv')
> location <- as.matrix(location)
Like I said, that can get a plot fine.
Should I use image or heatmap?

I am beginner and new to this -R world. I have heard much about R and
started working on it.

and values as their score for every month . I tried to generate a heatmap
with this data and got some good results. Can some one help me on how to

coloring dendrgram in heatmap?
Using the heatmap function in mva, it seems to be hard to use different
colors in the edges leading to different groups of objects, as commonly done
in many heatmaps in the microarray graphics. Any suggestions? Thanks.

lines() in heatmap()
Hello!
I looked for help through google and the help-files and spend several
hours with trial and
error, but didn't find a correct way.
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:

specifying colors in a heatmap/image -like plot
Hi,
I have searched for a solution but I failed to find an answer. I am hoping
you may be able to help me.
I have a data set where I have observations for a number of units (n =~40)
over a period of time (t =~100) and I have a variable (Z) that codes a
categorical variable for each observation. I want to produce a 2D plot where
time is on the x-axis and units are on the y-axis. Then each block

Heatmap/Color Selection(Key)
Hi
I made heatmap of QTL based on Lod score. Where I have traits in columns and
marker data (rows). I can not cluster both column and rows as I need the
right order for marker data.
Can someone suggest me better way of generating heatmaps especially the
colour key I want to select to visualize the results which are more
interesting to look at.

gridBase and heatmap
I would like to use gridBase to place four separate heatmaps (actually,
a stripped-down heatmap.2 from ght gregmisc package that contains only
the "image" part) into four different viewports. I can get the
placement correct, but I keep 'losing' the previous plot. Any
suggestions?

heatmap color distribution
Hi all,
I've got a set of gene expression data, and I'm plotting several
heatmaps for subsets of the whole set. I'd like the heatmaps to have
the same color distribution, so that comparisons may be made
(roughly) across heatmaps; this would require that the color
distribution and distance functions be based on the entire dataset,
rather than on individual subsets. Does

Could heatmap default to scale="none" ?
(I have searched the email archives for discussions on this topic but
have found nothing.)
The help page for heatmap says:
By default (scale = "row") the rows are scaled to have mean zero and
standard deviation one. There is some empirical evidence from genomic
plotting that this is useful.
I offer two comments on that.
1. Since the heatmap function is general-purpose (that is, not in

highlighting clusters in a heatmap
I would like to draw horizontal or vertical lines on a heatmap to
highlight the clusters at some specified cut depth of the dendrogram.
As a hacked example, the following code would work if I could set the
coordinates of the top and bottom of the false color image correctly
(ymin and ymax), but the correct values seem to depend on the output
device and its size. I realize that heatmaps use a 2x2
