creating rainbow gradients
Hi, how can I create a rainbow gradient in R? For example, let's say I have
a plot of y = x...and I want the plot to go from red -> orange -> yellow ->
green -> blue -> etc.
Right now, I know how to do something like go from red to blue, using the
plotrix library:

color2D.maplot fixed color range
Dear all,
I have
-one matrix sr ([200,200]) which is the original file
-25 matrixes estimatedsr ([200,200]) which are an estimation of the sr.
As I am plotting these matrixes I want to have ONE common way that the cells are colored. Eg. Values from 10-20--> red color, 20-30-->blue color (or something like that). This is the only way one can easily compare all these matrixes together.

combination of scatterplot and image graph
Dear R users,
I'm interested in a combination of a scatterplot and an image graph.
I have two large vectors. Because in the scatterplot some areas are
sparsely and others densely populated, I want to see the points, and
I also want their color to be changed based on their density (similar
to a heat map). Is there a function that can do that?
Thank you,
b.

Colour-coding intervals on a line
Hi,
This is a simple version of something that I am trying to do. If I can
sort the problem basically, I figure I should be able to sort it for the
program I'm writing (which would take longer to explain).
I need to know if there is any way of using different colours for
different intervals of a line on a graph. Eg. If I plot the line y=x for
x=1:10, and split this line into 106 intervals

Categorical bubble plot
Hi,
I do not have much R experience just the basics, so please excuse
any obvious questions.
I would like to create bubble plot that have Categorical data on the x and y
axis and then the diameter if the bubble the value related to x and y.
Attached to the email is a pic of what I would like to do.
I do hope someone can help me.

plotrix_3.2
Hi all,
plotrix 3.2 has arrived. The reason for this announcement is that there
have been a couple of major rewrites.
The barNest family of functions has had an overhaul that began as a fix
for an apparently trivial bug that caused problems with empty
subcategories. So far, testing has not found anything that will break
code written for the former version.

Question about graphics in R
Considering the R function/plot shown below, I wonder whether
it is possible to do the following changes:
(1) Change the color of each point to be picked from
list of colors according to its z-value. (The range
should be from blue (z=0) to red (z=1).) The grid
should then be omitted. [I have seen "terrain.colors", but
don't know how to use it for this purpose.]

Titles in MAplots
Hi
Does anyone know how to set the titles in MAplots to just show the CEL file name?
So far I have;
#define 'Array' as object containing CEL names
Array <- col.names(Data)

bmp("C:/MAplot%03d.bmp")
#remove the annotation and minimise margins

color2D.matplot not giving colors
I am using color2D.matplot to plot a matrix about 400 by 200.
The values in the matrix are 0:5 and NA. The resulting plot is not color, but shaded b/w. I tried to figure out how to add colors, I would like something like c(blue, green, red, cyan, green)
#example
motifx <- matrix(NA, nrow=100,ncol=20)
motifx[,1:5] <- 1
motifx[,6:10] <- 2
motifx[,11:15] <- 3
motifx[,15:19] <- 4

color2D.matplot axis names
Hi,
I finally came up with a nice colored matrixplot, using the color2D.matplot
function of the plotrix package. But I can't assign xtics and ytics to this
plot. I made sure that the matrix has correct colnames() and rownames().
Here's what I do:
a=matrix(1:16, 4, 4)
colnames(a) <- c("X1", "X2", "X3", X4)
rownames(a) <- c("Y1",

How to set Color scale for color2D.matplot()
Hello, everyone.
I am trying to show the correlation matrix using
color2D.matplot(). And I want to map (0,1) to (dark red to dark green).
But by default color2D.matplot() will map(min element of given matrix,
max element of given matrix) to (dark red to dark green).
Can anyone help me with this issue?
Thanks a lot!

NAs in color2D.matplot
Hi,
I am trying to plot a large matrix by using color2D.matplot. A substantial
part of the matrix has no data (NAs). However, when trying to plot it, I get
an error. It is only when I change all NAs to zeros that it works, but that
in some way introduces 'wrong' data. Is there any workaround this? Thank you
in advance!!!

Color2D.matplot uniform color range
Hi all.
I am having a problem using color2D.matplot
I am trying to visualize several different matrices under two color ranges.
One color range corresponds to values less than 1 and the second color range
for values greater than 1. However, the minimum value of each matrix differs
and is automatically set to have the smallest value in the color range.
Similarly, the maximum value of each matrix

Error in "color2D.matplot" : "Error in plot.new() : figure margins too large"
Hi,
I am using color2D.matplot (...) function of "plotrix" package. I used
a matrix of size around 20*20
However, apparently it failed to visualize the matrix and gave the
following exception, which I don't have any idea about possible source
of this error.

Plotting multiple xts/zoo time series on a single plot.
So I've got a 154 column wide xts time series object and I want to plot the
154 series on a single plot and have the added benefit of the time series
dates on the x axis.
Any suggestions for plotting functions, maplot works but does not give dates
on the axis and I can't seem to get plot to give me more than one series.

Fine Tuning Plotrix
Dear All,
Please see the code snippet at the end of the email.
I am using the color2D.matplot in Plotrix to plot a matrix.
It works great, but there are a few things I cannot figure out
(1) the value of cex.axis in the code snippet does not seem to affect
the final pdf at all (at least on my system, Ubuntu 9.10, plotrix and
Cairo installed from cran). How do I specify the size of the axis ticks
