Colorramp in Maptools, how to choose min and max values for the fg= argument
...lour of the region indicates some region dependent value
(population for example).
I pass the colours of the regions to the plot.Map function by defining
the foreground colour:
jet.colors = colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan",
"#7FFF7F", "yellow", "#FF7F00", "red", "#7F0000"))
n=100
cols <- jet.colors(n)
Intervalls = cut(as.numeric(Vector),n, na.rm=TRUE)
fgs <-cols[Intervalls] ## is there some option/possibility here to
choose colours differently ??
plot.Map(Shape.map, fg=fgs,...

why I could not reproduce the Mandelbrot plot demonstrated on R wiki
I am trying to reproduce the nice looking of Mandelbrot demonstrated by R
wiki page by the following code:
library(caTools) # external package providing write.gif function
jet.colors = colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan",
"#7FFF7F",
"yellow", "#FF7F00", "red", "#7F0000"))
m = 600 # define size
C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ),
imag=rep(seq(-1.2,1.2, length.out=m), m ) )
C = matrix(C,m,m)...

is it possible to create a trellis object with multiple colorkeys/z-scale axis?

latticeExtra tileplot question - tiles are not all the same size, need help.
...xtConnection(gsi_csv),header=T)
##Custom color ramp...I didn't like the ones that are provided in the
package, this is similar to jet colors in matlab
jet.colors <-
colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan",
"#7FFF7F", "yellow", "#FF7F00", "red", "#7F0000"))

need palette of topographic colors similar to topo.colors ()
...a great function for
creating your own palettes. For example, Matlab's jet palette (also
available in fields package under peculiar name 'tim.colors') can be defined
by:
jet.colors = colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan",
"#7FFF7F", "yellow", "#FF7F00", "red", "#7F0000"))
Other predefined functions for creating and managing color palettes that I
know of, are:
* R provides functions for creating palettes of continuous colors:
rainbow, topo.colors, heat.colors, terrain.colors....
