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.
There's a multitude of such mappings depending on the

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

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 so far I can

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

Bert answered your subject line question. Your text is asking something
else: if those are colours, you don't want to treat each of them as a

belongs_to relation busted....why?
Ok, been banging my head on this and just can''t figure it. Normally, any
table that has a belongs_to to another table you can easily access it
by:
table1.table2.field
And it works perfectly for one table I have. Let''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

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

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,

heres how to get color output in rspec_autotest with rspec 0.7.5
In case anyone else is trying to make this work, here is what I did
(Before 0.7.4 I had patched the regex in zentest redgreen, but that
is not used any more)
To use directly, it is very simple. In rspec_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

Creating a vector of colours that are as different from one another as possible
Hi
I want to create a vector of colors that are as different from one
another as possible. ?rainbow 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

change colour of geom_step by scale_colour_manual
Hi,
Color of my step plot is now by default. Now I'd like to change the color as
the grey scale I specified. I don't know why I got three black plot. Here I
attach two version of codes. The first one produces a step plot with color
by default. The second one, modified from the first one, is not producing
the grey scale I want. Any help would be highly appreciated.

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)

How would you calculate the "mean colour" of several colours, for

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'm

2d plotting and colours
Hi!
I am new to R just 3 days in it and i apologize if my questions seem very
trivial and consumed your valuable time.
I am coding in perl and i stumbled upon R regarding plotting good
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

Colour gradients and colour fill between points
Hello,
Can somebody help me on a colour question?
I have a levelplot made with the following syntax:
library(lattice)
inp <- read.csv("hoenne1", header = TRUE)
levelplot(z~x*y, data = inp, region = TRUE, pretty = TRUE, col.regions
= terrain.colours)
The file "hoenne1" contains the data. I'll give a short example:
x,y,z
0,0,1
0,1,1
0,2,1
1,0,2
1,2,2

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
