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 ========================================================================= library(ggplot2) xx

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

Colour filling in panel.bwplot from lattice
Inspired by colouring the dots of box-whisker plots I am trying to also fill the boxes (rectangles) with different colours. This seems not to work as I expected. Looking at the help page of panel.bwplot it says: ''fill - color to fill the boxplot''. Obviously it is only intended to fill all boxes wit...

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

Colour points in plot according to third variable
Hi, I am using the plot function to make a simple plot of my data with one variable against another and want to colour the data points according to a third variable. The third variable is continuous (Time) and I want to try two different ways of colouring the data points, either: Divide time it into three groups and then colour each data point accordingly eg. 30-60 minutes in green, 60-90 minutes in red and 90-120 minutes in blue.. or, Colour the data points using a colour gradient eg. with increasing colour intensity as time increases..

Now I have a second set of z-values(x,y-values same as the first surface), which I would like to make visible on the same graph, however, not as a surface, but rather as coloured contour on the first surface, so that the resulting graph will consist of the original surface having the colour of the second

How to turn the colour off for lattice graph?
Dear All, I am trying to plot a lattice figure and include it in a LaTeX document via the TikZDevice package. I think the journal I am submitting to does not like colour figure, so I need to get rid of all the colours in the figure. If I directly generate PDF or EPS, the option "trellis.device(color=FALSE)", but when I do: trellis.device(color=FALSE)
