axis tick colors: only one value allowed?
...nts to the
plot routines (albeit pretty silly enhancements).
As another side note: calling rug() with color set to '#00000033' lets
you see dense regions as darker than sparse regions, without having to
resort to calling jitter() first.

plotting with a symbol on every nth point
Hi,
I would like to produce a plot with a symbol on every nth point in a time
series data, like the one in the following:
http://www.phon.ucl.ac.uk/home/yi/ProsodyPro/EnglishFocus.png
x <- seq(-100,1000,25)
plot(x,type="l")
Could someone help me out with the above example?
Thanks....

place values into a matrix efficiently?
...f the original data(x vs y) that looks
like plot(x,y) .
Anyway, I just seem to be blanking: is there some vectorized way to
place values, or even a constant value, into all elements of xymat whose
row,col coordinates match ordered pairs in x and y ?

Polygon
Hi everybody,
I have a matrix with 3 columns (Date, MeanArea and SdArea). I want to draw a
figure showing the variable MeanArea in terms of the Date. But instead to
use the variable SdArea as bar error, I want to use ?polygon error?. I use
this code but the output does not seem good.

palettes for the color-blind
Everyone,
I'm working with scatter plots with different colored symbols (via
lattice). I'm currently using these colors for points and lines:
col1 <- c(rgb(1, 0, 0), rgb(0, 0, 1),
rgb(0, 1, 0),
rgb(0.55482458, 0.40350876, 0.04166666),
rgb(0, 0, 0))
plot(seq(along = col1), pch = 16, col = col1, cex = 1.5)
I'm also using these with transparency (alpha

Putting an index explicitly into function code --- a curiosity.
I want to create a list of functions in a for loop, with the index
of the loop appearing explicitly in the function code.
After quite a bit of thrashing around I figured out how to do it.
Here is a toy example:
junk <- vector("list",4)
for(i in 1:4) {
itmp <- i
junk[[i]] <- eval(bquote(function(x){42 + .(itmp)*x}))
}
So I'm *basically* happy, but there's

Solving Equations
People,
I'm researching some Bayesian statistic topics and in the midle of my study
i found a very simple problem and i'm trying to find a simple package to
solve this type of equations:
Lets say that i need to compute beta values for the beta distribution and i
now for example:
E(teta)=a/(a+b) = 0,5
Var(teta)=ab/((a+b)^2(a+b+1))=0.05
So if i want to solve this to non-linear system to

an unusual use for R
I thought some of you might be amused by this.
In my non-work time, I'm an avid weaver and teacher of weaving. I'm
working on a project involving creating many detailed weaving
patterns, so I wrote R code to automate it.
Details here:

tip: large plots
Hi all,
I'm working with a bunch of large graphs, and stumbled across
something useful. Probably many of you know this, but I didn't and so
others might benefit.
Using pch="." speeds up plotting considerably over using symbols.
> x <- runif(1000000)
> y <- runif(1000000)
> system.time(plot(x, y, pch="."))
