Hi Pachapep,
You can also do it like this:
library(plotrix)
plot(1:10)
# show color.scale(1:50,c(0,1,1),c(0,1,0),c(1,1,0),)
gradient.rect(1,4,10,6,c(0,1,1),c(0,1,0),c(1,1,0))

ok, I think I got it. Here is the code I used. Thanks for the help guys..
fake <- cbind(c(1,2,5,8,12,19), c(2,5,8,12,19,20), c(1,1,1,1,1,1),
c(-10,-10,-10,-10,-10,-10), c(10,10,10,10,10,10), runif(6, 0, 2), runif(6, 0,
2))
datalim <- c(-0,10)
matrix3plus <- fake[,-(1:2)]
dimnames(fake)[[2]]
Sorry for bugging you again. I was wondering whether it is possible to include
multiple different colors instead of just two.
In the example below, the color.scale() function goes from yellow to red, but
never passes through plain white. Would it be possible to tweak the function or
would I hav
Great, it works perfectly! Thanks so much for the awesome help!

Patrick,
No error in your code, just two different ways of deriving a range of
colors ... heat.colors() and color.scale(). I modified the code to just
use color.scale(). You can tell it what two colors you want it to use for
the extremes, and it will work out the shades in between.

Hi Jean,
Thanks for the great help. Indeed, it seems that that helps a bit. However, I
included a ‘control’ column made of ones.

However, the color doesn’t correspond to that
Hi Jean,
Thanks a ton for the help. I think Im almost there, but there is still
something weird about my stuff.
I have been able to understand the color.scale() function. Now, I am trying to
plot a key for the corresponding colors. The function is called ColorBar, which
apparently works - the
Patrick,
Thanks for providing reproducible code!
I think the main problem was that the extremes= argument in the
color.scale() function wants a range (a vector of length 2), and you were
providing with more than that, length(lut) is 10.
In the process of tracking this down, I made a bunch of min
Patrick,
You should cc r-help on all correspondence so that others can follow the
thread.
The color range will be matched to the "x" argument you provide to the
color.scale function (in package plotrix). So you don't need to manually
provide the min and max yourself. If for some reason you did
Patrick,
You were pretty close.
To fix the code you have, just change "matrix" to "mymatrix" in two places,
and either specify the argument data= or place the heat.colors bit first in
the matrix function.
Or ... you could use the array() function instead, to shorten up the code a
little.

Hi all,
I have a matrix which I want to plot in color. I have extensively looked at
level plot and heatmap/heatmap.2, but I would like to be able to manage the
size of the bins (boxes) on my X axis. So I thought of simply using the rect()
function, but I can’t get around assigning the correct c
11 matches
