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

issues with gap.plot function
Dear all:
I have the following codes:
Xdata<-c(2,3,8,9,10)
Ydata<-1:5
gap.plot(Xdata, Ydata,gap=c(5,6),gap.axis="x",type="o")
However, the type='o' seems only work on the first part of gap plot, the second half of the plot always just points, you can not add lines on that part, any help will be highly appreciated. I would like to have these two parts of

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!

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.

It would be appreciated if someone points me to the right origin

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

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!!!

gap.barplot doesn't support data arrays?
I am trying to make a barplot with a broken axis using gap.barplot (in the
indispensable plotrix package). This works well when the data is a vector:

> gap.barplot(twogrp,gap=c(8,16),xlab="Index",ytics=c(3,6,17,20),ylab="Group

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:

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

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

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,

y-axis in histograms
Dear R- list,
I have some data to present with histograms. Therefore I used hist(...).
I have few values with almost 80% of
the frequencies (totaly 800) and some other values with low frequencies
( totaly 5 -10 )
that I want to emphasize. Therefore I want to "cut" the y-axis on 100,
but I
don't know how to deal with this.

graph woes
Hey Gang,
Here is the situation. First of all I am a newbie, in the arena of R,
so please bare with me. I am trying to make a plot with a series of
plot lines that uses logs on the x axis, and when I plot it I am
having a few odd things go on that I do not know how to correct.
