R help - Mar 2008 - 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.
   
  Regards,

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 :

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))

    I used ?image function to do that, like below :

  image(x, y, r, col=gray((0:32)/32))
  

  However my next problem to add a color pallet for color description [as shown
in following link]. If anyone here tell me how to do that, it will be good for
me.

  What is the problem you are trying to solve? Tell me what you want to
  do, not how you want to do it.

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.
