voronoi.mosaic chokes?
Hi all,
I am running R 2.5.0 under Windows XP Media Center Edition. Here's a
problem that's been stumping me for a few days now, and I can't find
anything useful in the archives. I am using voronoi.mosaic (tripack
package) to create proximity polygons for a study of vegetation
competition and dynamics. The points lists are read in from a file for
each plot, then 8 duplicates

A comprehensive manual on "How to plot" (a lot of graphical examples welcome)
Hi,
I'm looking for a manual (we based or pdf) which would explain in detail
with graphical examples what all the option can do in plot and par. Does
anybody now anything like this? A couple of manuals to R I went through do
have plot parameters mentioned, but sometimes it is hard to understand or
imagine what the parameter can do (the same with the related help page)

StatsRus and wiki
Hi Jack:
Based on what you wrote in your mail about your hypothesis, I recommend you "StatsRus" website by Prof Paul Johnson. It's an excellent collection of R code snippets, and a veritable online oyster containing pearls of his wisdom :). Here is the link:

Possible to write text inside a bar of a barplot?
How can I write text inside a bar of a barplot? I tried using text(), but I
am only able to specify the numeric y-coordinate. The different columns of
my barplot correspond to factors and not numbers, so I don't know how to
access the horizontal positions of the bars. I tried fiddling with different
values of the "adj" argument, but this appears unreliable.

Treemap lost data
First: Im sorry for my bad english ;-)
I use "portfolio" to create treemaps with "R".
I've got a .csv dataset of all the schools in my city, containing 6
variables each with 1469 lines of data.
When I create a treemap, 3 of these schools were not taken into account by
"R". I dont know why. It doesn't matter where I put them in my dataset, they

Drawing paths through a grid
I would like to draw a set of points that are equally spaced in a 2-D
grid. Then I would like to draw lines that illustrate different
directed paths through subsets of points. Imagine that the points
correspond to booths in a conference center, and I want to show the
various paths people took to visit the booths (using color to
highlight different types of paths). An example path might be: [(1,1),

Newbie mistakes saving images to files
I am encountering problems using the png() function to save around 20 charts
to separate files.
My script is conceptually structured as follows:

barchart, etc. with special arguments.

Barchart bar lengths not proportionate
When I use barchart (with default formatting options), I get bars whose
lengths/heights are not proportional to their value. For example:
http://drop.io/wbagm6s/asset/capture-png
Many of the values in this chart are 1; however, because the blue bars
extend to the left of the "0" tick mark, those bars appear to represent
higher numeric values. Is there a way to make the length of the

Treemaps
Has anyone implemented "treemaps" in R?
A "treemap" is a visual display of a tree structure in which, at each level,
the several nodes are represented by rectangles which fill the available area.
The areas of the rectangles represent size, and their colors represent some
other variable. There are several algorithms for deciding how to place the
rectangles, ref:
