color2d.maplot error
Dear all
I am using color2D.maplot to map some matrixes to plot. everything works fine. It seems that when my matrix contains only the same value color2D.maplot returns the following error:

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.
"Error in plot.new() : figure margins too large"
It would be appreciated if someone points me to the right origin

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.

Help with matplot
Hi, I apologise in advance for the na?ve question. I have large matrices that I want to plot. I currently use color2D.matplot. However, these matrices contain many values of no interest (i.e. where there is no data, the figure -999 is automatically displayed). Is there any way of removing these from the matrices to be plotted by matplot? An obvious possibility is setting them all to 0, but that

plotting issues with PCA
Hi Listers,
This has a simple answer but it has been eluding me nonetheless.
I have been building a PCA plot from scratch with the ability to plot
predefined groups in different colors. This has worked fine but when I try
to get a polygon drawn around each of the groups it is not recognising my
colour file correctly and is only printing the first colour in the
file....code is below

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

Plotrix Trick
Dear All,
I am using the plotrix library to plot some matrices.
I have a problem: some of my data are outliers, hence using a linear
color scale does not work very well (you would see too many cells having
a similar, indistinguishable color). See the code snipped at the end of
the email.
Plotting the logarithm of the data gets the job done, but my problem is
that I would like to write in every

Colored boxes with values in the box
Hi all,
I have a x, y matrix of numbers (usually ranging from 0 to 40). I need
to group these numbers and assign a color to each group (for example 0
to 15 - Blue, 16-30- Yellow, and 31-40- Red). Then I need to draw a
rectangular matrix which contains X x Y boxes and each box has the
corresponding value from the input matrix and is also colored according
to which group (i.e red, yellow,

plotting many unique colors with categorical data

color to represent each individual factor. For example:

Log color scale
Hi all,
In response to a previous post about plotting a numeric square matrix
as a colored matrix, I was referred to both image and the
color2D.matplot function in the plotrix package. Both have worked for
me thanks!!
However I need to plot my data in a log transformed color scale. Is
this possible? I will be happy to explain further, but basically I
need to do this because there are large

Hexagon border in plotrix's math2D.plot
Hi there,
I'm attempting to use
color2D.matplot(x,cellcolors=cellcol, do.hex=TRUE)
from the plotrix package, but do not want to have borders around the hexagons. I've tried various approaches such as
fg="white", col="white", lty=0, lwd=0 and border=NULL/FALSE/"white", but none of them works.
I'd appreciate any ideas.
Thanks,

(no subject)
Hi all,
I am looking for a clever way to create the following graph using R:
I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color.
Is there a clever of doing this?
Thanks for your help

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.]
(2) Add two lines to
