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()
heatmap.2(mat, Rowv=NA, Colv=NA, col=redgreen(75), symm=TRUE, trace="none",

how to inspect content of save file
Is there a way of listing the variables contained in a file created
with the save() command other than load()ing the file?
I have a couple of rather larger files that I would rather not load ...

using k-means clustering in conjunction with heatmap.2 function
Hello,
I am trying to create a heatmap that clusters based on a k-means scheme
rather than a hierarchical clustering scheme.
Suppose I have the following input data, located in sample.table:
x1 x2 x3 x4
x1 17.198 16.306 16.806 16.374
x2 14.554 10.866 15.780 14.596
x3 14.374 14.118 14.569 17.352
x4 17.505 14.596 15.738 14.070
By using the heatmap.2 function as follows, I can create a heatmap

resampling for correlation and testing
Hello all R-er,
I'm trying to run a resampling method on some data. The current method I have takes 2+ days or a lot of memory . I was wondering if anyone has a better suggestion.
Currently I take a matrix and get the correlation matrix from it. This will be called rho.A. Each element in this will be tested against the distribution from the resampled correlation B matrix.

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:

The question is on Symmetry model for square table.
Please help,
I tried a program on S-plus, and it worked. Also I tried the same
program on R but not worked. Here is the programme. I put it in a
function form. The model and assumption are at the bottom.
where
counts<-c(22,2,2,0,5,7,14,0,0,2,36,0,0,1,17,10)
which is name.data, i is row size and j is the column size.

Rspec autotest error
Hi all,
I tried testing with Rspec for first time, following a tutorial.
"rspec spec/" works fine but when I try ''autotest'' it gives me the
error message below. I also made a gist about it: https://gist.github.com/779265
It seems like a redgreen or ZenTest error. I''m using Ubuntu10, Rails3,
Ruby 1.9 and RVM. Any help is appriciated, thanks in advance,

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.

hclust and heatmap - slightly different dendrograms?
Good afternoon,
I ran heatmap and hclust on the same matrix x (strictly, I ran
heatmap(x), and hclust(dist(t(x))), and realized that the two
dendrograms were slightly different, in that the left-right
arrangement of one pair of subclusters (columns) was reversed in the
two functions (but all individual columns were grouped correctly).

reordering materix presentation in heatmap.2 in the 'gplots' library
Dear R users,
I'm trying to create images of 2 symmetrical matrices using heatmap.2 of the 'gplots' library. Both matrices have the same row and column names
For the first matrix I'm using the default clustering and column denrogram options:

heatmap.2 in gplots package
Hello all,
I am using the heatmap.2 function in the gplots package. I want to supress the reordering of the columns of the data matrix i pass to the function. I used the statement,
heatmap.2(z,Colv=FALSE,dendrogram="row",col=redgreen(75))
where z, is the matrix of data. The output i want should have the rows reordered along with the dendrogram and the columns should be in the original

Unexpected behaviour for RowSideColors in function heatmap
Hello,
I have come across some unexpected behaviour of the function heatmap in the stats package. This looks like a bug to me, but I might have misunderstood something.
When calling the function in symmetric mode, the ColSideColors are plotted correctly, but RowSideColors appear in reverse order. This code (modified from the example on the help page) demonstrates the problem:
