heatmap ordered list
Hi,
another problem on heatmaps... after generating the graph with
myBlRd <- colorRampPalette(c("blue", "red"))
heatmap(dataHeat[Top100, ], col=myBlRd(15))
i need to retrieve the row names' list ordered by the dendrogram.
I tried with "rownames(data)[Top100]" but the list is not ordered
(as i can see in the generated picture). Any tips?
Tnx

create a color palette with custom ranges between colors
Hello everybody,
I'm trying to create my own color palette on R, in order to interpolate some
different temperature data on different maps (daily means, seasonal
means,...).
I would like to create a color palette which works for each map, so I need a
color palette between -40 and +40?C. Sometimes my data for one map range
from -10 to +20, sometimes from 10 to 30, etc... but always between

color gradation inversion.
Dear list
I'm having trouble with inverting color gradation.
As seen in the "rgl" example,
library(rgl)
example(rgl.surface)
I understand that I can assign colors to heights for each point.
col <- colorlut[ y-ylim[1]+1 ] # assign colors to heights for each point
However, I am now trying to assign inverted colors.
(top colored green, and bottom colored gray).
Is there any

Converting a data frame to matrix
Hello:
I have a tab delim file with 100 rows and 100 columns.
I have numerical values in this table. What I want is to create an image
color map with color gradation.
my values range from -5 to 0. max value is 0.
to acheive this, I need to convert my data.frame into matrix.
I tried following :
mydf <- read.table('mytable',sep='\t',header=T)
mydf1 <- mydf[,2:100]

heatmap.2 and three colours for specific ranges
Hi,
I hope to show a heatmap with thre colours, no gradation. How to specify
heatmap.2 to map "green" for values less than -1, "gray" for values between
-1 and 1, and "red" for values greater than 1 ?
Thanks

spplot modifications

I need a little help making modifications to the image included with this
post. First, rather than using a linear color legend to display the output
I would like to use a log-scale legend. Thus, the legend on the right would
go from 1 to 1000, for example, with a classic log-scale gradation. What I
hope to avoid is taking the log of the

Request for Comments: Upgrades from 3.x to 4.0+
Hi Amudhan,
Please go through the following that would clarify up-gradation concerns
from DHT to RIO in 4.0
1. RIO would not deprecate DHT. Both DHT and RIO would co-exist.
2. DHT volumes would not be migrated to RIO. DHT volumes would still be
using DHT code.
3. The new volume creation should specifically opt for RIO volume once
RIO is in place.
4. RIO should be perceived as

heatmap with levelplot?
Hi,
How do I anchor z=0 to the white color in a levelplot so that
the color changes from cyan to magenta precisely as
z changes from negative to positive? Also is it easy to change
color scheme, say to blue/red as it's more dramatic? Is there a
better function for showing heatmap with a color bar?
Thanks in advance for any help, I've played with image,
heatmap and levelplot a little and

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

color palette heatmap
Hi,
I'm kinda new of the R world.
I need to use the heatmap or heatmap.2 function to plot correlation values.
2 questions:
- how can I specify a color palette? (would like to have a transition from
blue(-1) to white(0) to red(1))
- how can I use heatmap.2 imposing a specific order (like hclust.order)?
I mean, I don't want heatmap.2 to re-cluster/re-order my data but just to
plot them

HELP ON SCALING GENE EXPRESSION DATA TO -1,0,1
Hello R-Community,
I am a rookie in R and I am fascinated with the power of bio computing
by R. I am analysing gene expression data from Real time PCR. I have
used absolute gene quantitation to measure gene copy number in all my
transcripts. All my data has been normalised them to a housekeeping
gene, which is constitutive expressed.
My problem is as follows.

repeating symbols and colors
Here?s an easy one. Well, easy for those more clever than I am.
I am plotting several groups and use symbols 15:25, pch <- 15:25
Sometimes, however, I need more than those and would like to have them
recycled automatically so that pch[12] = pch[1]. Perhaps I can use %% or
kludge up a multi-line, multi-if solution, but hope that a kind helper can
suggest something more elegant.

does RIO improves folder listing and rebalance, when compared to 3.x?
if yes, do you have any performance data comparing RIO and DHT?
