Colour Schemes
I've been thinking hard about generating colour schemes for data.
There's quite a bit of existing code scattered in various packages for
playing with colours and colour palettes, but I can't find the sort of
thing I'm after for applying colours to data...
To my mind a colour scheme is a mapping from data values to colours.

Natural colours for topographic data
Dear list members
I'm currently working on some topographic (elevation) data, and was
somewhat surprised that the 'topo.colors' and 'terrain.colors' are of
little to no use here.
The problem is that these functions only return a palette of colours;
they don't map depth values to colours. So if I plot (using 'image',
'persp' or similar functions) and specify these palettes, ocean areas
may coloured green (indicating) land, which may be quite confusing.
I have looked through various packages, and have found several col...

VNC 'fix' for 256 colour game only shows 2 colours?
I'm trying to run an old (~1995) Windows game under Wine, but it requires 256 colours and won't work any higher. I've checked out the 256 colour hacks page and the X methods don't work, because I use the FGLRX drivers and they don't support 8bpp, so I'm trying VNC.
I've installed vnc-server and vnc so I can play it through a 256 colour VNC connection, but s...

ggplot: colours to geom_segments
Just as an exercise I am tying to add colours to a geom_segment command. I can get one colour but not a sequence of colours.
Can anyone suggest how I can get the green lines in the plot below to be different colours? I thought I could use a palatte of colours but that did not seem to work.
Thanks

belongs_to relation busted....why?
...39;'s call it... tags. So,
I''ve got:
Tag -> has_many :blah_tags
Blah -> has_many :blah_tags
Blah_tag -> belongs_to :tag, belongs_to :blah
Ok, works fine. Based on a blah_tag entry, I can go blah_tag.blah.name
(or whatever). No problem.
Substitute, an identical setup for say Colour, and bam. The whole thing
throws nils everywhere. I may have a big batch of valid colour_tags, but
try to go: colour_tag.colour => NIL!
I don''t get it. Identical table setups....identical code.... is colour
reserved? Do I need to restart servers or something (tried that...)? Am

filled.contour: colour key decoupled from main plot?
Dear R colleagues,
I am trying to plot some geophysical data as a filled contour on a continent map and so far the guidance from the R-help archives has been invaluable. The only bit that still eludes me is the colour key (legend) coming with filled.contour:
I prefer to generate my own colour palette, mainly based on the quantiles of tenths of the data in order to capture the whole range (of rainfall for example), including the more extreme values both sides. In the colour key this results in uneven distributio...

Getting rid of borders on semi-transparent plotting symbols
R version 2.7.0 RC (2008-04-20 r45403)
When using semi-transparent filled plotting symbols, the border of the
symbol has a different (darker) colour than the interior:
plot(0, 0, pch=19, col="#FF000022")
(Saving this as a PDF and looking at it magnified may make it easier to
see.)
This is pretty annoying, since when plotting partially overlapping
points, the border colour dominates, making the colour of overlapping
points more sa...

heres how to get color output in rspec_autotest with rspec 0.7.5
...pec_autotest/lib/
rspec_autotest.rb, add a -c to the spec_command in the initializer
function:
@spec_command = "spec -c --diff unified"
This won''t help however if you want to use rails_spec_server. To do
that I patched rspec_0.7.5 to add an option to force the adding of
colour codes (I did it this way because I assumed the check for
output==Kernel was important for some other situation and I didn''t
want to just throw it away):
diff -upr rspec-0.7.5/lib/spec/runner/formatter/

Creating a vector of colours that are as different from one another as possible
...ainbow states "Conceptually, all of these
functions actually use (parts of) a line cut out of the 3-dimensional
color space...". This suggests to me that the resulting colors are all
placed on this "line" and are equi-distant along it. The resulting
color palette is a range of colours where adjacent colours are actually
quite similar, especially when n (the number of colours) is high.
Conceptually I guess what I want is colors from a 3D polygon in 3D
colour space, where the number of vertices in the polygon is n,
resulting in a color palette where the colors are all quite diff...

Help with plotting a line that is multicoloured based on levels of a factor
Hi All,
I'm trying to plot data that is a time series of flows that are associated
with a specific level, and I would like each level to represent a colour
in a line plot. Here is some data that approximates what I'm using:
date=c(1:300)
flow=sin(2*pi/53*c(1:300))
levels=c(rep(c("high","med","low"),100))
data=cbind.data.frame(date, flow, levels)
the "levels" column represents the levels of flow....

Plotting a grid of directly specified colours
Dear R-help,
Could any of you direct me to a function for plotting a grid of colours,
directly specified by a matrix of hex colour codes? In other words I'm
looking for a heatmap() or image()-like function to which I can specify the
colour of each grid location directly, rather than providing a numerical
matrix and a 1D-colour scale (heatmap, image, levelplots,NeatMap...). I&...

2d plotting and colours
...ood
statistical graphs.
I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried
the example code given in the tutorial to perform 2d plot
# i ranges from 2 to 10
cl <- kmeans(x, i, 20)
plot(x, col = cl$cluster)
points(cl$centers, col = 1:i )
I see that there are only 8 colours defined , namely
black,red,green,blue,cyan,magenta,yello,gray.
How should i set my colour preferences to obtain my palette of colours? I
checked in the totorial which talks about R.colors and palatte , but i
failed to understand how to set it.
Thank You

setting specific colours for different groups of points on a scatter plot
Hi,
I have a table with three columns of data, let's call these a, b and
c. I have produced a scatter plot of a against b, but I would like to
colour the points according to their corresponding c values. c takes
the value of either 0,1,2,3 or 4 and so I would like to colour all of
the points with a c value of 0 one colour, all those with a c value of
1 another colour etc. When I use the following code, it colours the
points using default...
