Lattice package par.settings/trellis.par.settings questions
Hi All,
I'm trying to modify some of the default graphic parameters in a
conditional histogram. While I was able to change the default grey
background to white, I couldn't change the axis.font or the xlab font.
I used the following code:
/histogram(~V751|V013+V025, finalbase, xlab="Heard of HIV/AIDS

trellis.par.set and grid : how to set by default that I want a grid on my graphes ?
Hello all,
I want to draw a grid behind my graphes, using lattice package.
I manage to do it with instructions like this one :
xyplot(Sepal.Length + Sepal.Width ~ Petal.Length ,
data = iris, allow.multiple = TRUE, scales = "same",type="l",
panel = function(...) { panel.grid(h=-1, v= -1) ;
panel.superpose(...)
}

white in the default palette
Dear All,
[I'd already sent this message earlier (Apr 6) but as I had no response
and I still see that it is the case in R1.5 I thought I'd try again]
I recently encountered a problem (actually missed some data) because
"white" is one of colours in the "default" palette and that does not
show up to well on my transparent (on white background). Of course it is

heatmap with levelplot?
Hi,
How do I anchor z=0 to the white color in a levelplot so that
the color changes from cyan to magenta precisely as
z changes from negative to positive? Also is it easy to change
color scheme, say to blue/red as it's more dramatic? Is there a
better function for showing heatmap with a color bar?
Thanks in advance for any help, I've played with image,
heatmap and levelplot a little and

Colours for 3-way probabilities
Are there any R functions for creating palettes for three-way data?
For example, election maps for three parties where pure red, blue, and
green show 100% for the Red, Blue, and Green parties respectively,
magenta shows a 50-50 Red-Blue split with 0 for the Greens, cyan a
50-50 Blue/Green split with no Red votes and so on, with grey, black
or white at a 1/3,1/3,1/3 split vote.

Drawing a colour wheel - bug in hcl?
Hi All,
I'm trying trying to draw a colour wheel (a slice of hcl space) in R.
Running the code below doesn't give me what I expect - there's some
oddly bright colours of the wrong hue around c(0, 0) and I see three
coloured circles (a small magenta, a medium sized yellow and a large
cyan). Am I doing something wrong or is there a bug in the hcl code?

fancier plotting
Hi
thank you for talking the time to help me with this.
I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e
2 a show a green dot
4 b show a

create waveform sawtooth
My tuneR sawtooth wave function generator is broken.
When I use the sine function, I get exactly what I expect: a sine wave whose frequency is defined by the freq parameter. In particular, higher frequencies have shorter wavelengths (more cycles per second means shorter waves). When I create a sawtooth wave, the opposite seems to occur: higher frequencies result in longer waves. But that?s not

create waveform sawtooth
Ccing the maintainer if the tuneR package.
Looks to me like sawtooth (and square) don't behave as expected when using xunit="samples". Workaround is to use xunit="time" instead:
sawtooth(110,duration=1/100,samp.rate=sample_rate,xunit="time")
I looked at the code but found it to be opaque.

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
cl <- kmeans(x, i, 20)

Colour palette goes nuts.
Not sure how to describe this or where to point the finger, so I thought I
post here before submitting a bug.
Wine: 0.9
Application: Titanic Explorer
This application is a 'educational' triple CD about Titanic. It is created
with macromedia 'director 6' and utilizes QuickTime.
It installs fine.
Runs fine (needed to disable ddraw on QuickTime) until I try a 'search'.

Adding Mean to Notched Box Plots
Hello everyone,
I'm new to R and made my 1st notched box plots this weekend. I've read some
of the other post regarding adding means to box plots but I'm still having
problems.
I've looked at some of the other discussions and R News Volume 3/2, October
2003 which had info also but all these seem to address "groups" of data.
I have some rainfall pH data from
