Re: [R] How to create following chart for visualizing multivariate time series
Let me take an artifical matrix :
dat = matrix(rnorm(200*200), 200, 200)
My goal is to visualize this matrix according to the procedure, described in
previous mails. I took Mendelssohn's advice and got following advice :
?plot.im
Z - setcov(owin())
plot(Z) etc
However I can not reproduce this example in my problem. How I can change my
data matrix 'dat' to 'Z' ?
If anyone show me some light it would be great for me.

What you are after is a colorbar. There is a colorbar option in the GLAD
package in Bioconductor. See also the response at:

Hi Jim, i think you could not get my point. I did not want to put red-blue
color there. I want to put a pallet which will describe the values of r. please
have a look on following :
http://bp0.blogger.com/_k3l6qPzizGs/RvDVglPknRI/AKo/itlWOvuuOtI/s1600-h/pairwise_kl_window60.png.
Please see how a color pallate is added on the right side of this plot
describing the value of red color, value of blue color etc.
Is there any solution?

Try something like this:
require(grDevices) # for colours
x - y - seq(-4*pi, 4*pi, len=27)
r - sqrt(outer(x^2, y^2, +))
image(x, y, r, col=gray((0:32)/32))
colors - colorRampPalette(c('red', 'yellow', 'blue')) # create you
color spectrum
image(x,y,r, col=colors(100))

However my next problem to add a color pallet for color description [as shown

following advice :
It is unclear a) which emails, since you have been having an offlist
correspondence with Mendelssohn, and b) why Holtman's solution offered
two weeks ago is not satisfactory.
As a reminder, it was, with very slight modifications:
colkey - colorRampPalette(c('red','blue'))(32)
levelplot(dat, colorkey=list(col=colkey),
col.regions=(col=colkey))
If the problem has changed then perhaps a new posting with a subject
line that matches the question and content that is self-contained would
be more effective.
