carpet plots

Hi all,
I wonder why there is so little software for carpet plots (german:
Rasterdiagramm) (Three dimensional plot (x, y, z), the 3rd dimension
(z) symbolized by colourgradients). Besides from one or the other non
free software I only found an OpenOffice macro, a combination of
Gnuplot and Excel (an Excel macro calling gnuplot)
(http://www.johannes-hopf.de/2009/12/carpet-plot-version-1-3/9 and
Quikgrid (http://www.galiander.ca/quikgrid/) which I use for
bathymetric maps.

Though I use one or two R scripts I have no deeper knowledge. Because
I think "That's a thing R can do!", I suppose, there are scripts for
this purpose. Perhaps one of you knows such a script. I would be very
grateful if you could point me to some information on this subject.

Richard

You need to expand you search list:

?heatmap
?levelplot
?contour
.... and many others

Here's an example with base graphics cobbled together from the last
example on help(contour)

image(x,y,volcano)
line.list <- contourLines(x, y, volcano)
contour(x, y, volcano, col = tcol[2], lty = "solid", add = TRUE,
vfont = c("sans serif", "plain"))
templines <- function(clines) {
lines(clines[[2]], clines[[3]])
}
invisible(lapply(line.list, templines))

# I did say "cobbled",

code.

tcol <- terrain.colors(12)

Re: carpet plots

In reply to this post by Richard Müller

These "carpet plots" are also called "heat maps" and there's a current thread with the subject line "Heat Maps" in which I've given a couple of examples of code for them. The R function image() is very easy to use:

image( x=(x values), y=(y values), z=(matrix of z values with x rows and y columns), col=(vector of colors), breaks=(vector of break points, one more than colors) )

What I'd like to know is: does anyone know how to easily create a legend/key to the color gradients, like the one in the right margin of Mueller's first example: (http://www.johannes-hopf.de/wordpress/wp-content/uploads/2009/12/Zufall-300x225.png)?

Also for base graphics fans:

?filled.contour # ...... and its first example
filled.contour(volcano, color = terrain.colors, asp = 1)# simple

Hi Joseph,
Have a look at color2D.matplot and color.legend in the plotrix package.
There is also sampcolorlegend in the shape package.
