Lattice densityplot with semitransparent filled regions
Hello,
I'm doing some graphics for a paper and a need customize such with filled
region above the density curve. My attempts I get something very near what
I need, but I don't solve the problem of use semitransparent filled. Below
a minimal reproducible code. Someone has any idea?
require(lattice)
# toy data...
dt <- expand.grid(A=1:2, B=1:3, y=1:50)
dt$y <- rnorm(nrow(dt), dt$B,

how to fill the area under the density line with semitransparent colors
Dear R-listers,
I have created a plot to display the density lines for the same
variable by different entities. Now, I want to fill the area under the
density lines with semitransparent colors.
Though I have checked that in web-searching and book-reading, I still
do not perform that.
Could anyone please give me any helps or advice? Thank you in advance.
The data and code I used listed below:

3D density plot of point set
...reate a contour density plot that would show a surface of constant
density which includes e.g. 50% of the points. Ideally, the surface
would be semitransparent, such that I can show two or three at the
same time.
Alternatively, if I would calculate the contour surfaces myself,
could I use R to semitransparently visualize a triangulated surface?
Thank you very much for your help

How to use alpha transparency channel for colors?
The release notes for R 2.0.0 states:
It is now possible to specify colours with a full alpha
transparency channel via the new 'alpha' argument to the
rgb() and hsv() functions, or as a string of the form "#RRGGBBAA".
NOTE: most devices draw nothing if a colour is not opaque,
but PDF and Quartz devices will render semitransparent colours.
A new argument

Online backup with dovecot
Hi!
Do you guys/girls (whichever you prefer) know if it's possible (i.e. in
some semitransparent/easy way) to incorporate an online backup system?
If the mail is older than a set amount of days it gets compressed.
I want my mail storage size to shrink but on the other hand I want to
keep the mails I get and have them easily readable :)
I'm thinking of symlinks and some kind of gzip

need for speed on grid.rect
When I use grid.rect to print a multi-coloured grid, it is incredibly slow compared to a single colour grid, or even a two colour grid.
I've set out some simplified examples below. This is something I run literally thousands of times a day, so I would greatly appreciate any hints on how I might improve the speed???

different colors for two wireframes in same plot
Hello R,
According to:
g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2)
g$z <- log((g$x^g$g + g$y^2) * g$gr)
wireframe(z ~ x * y, data = g, groups = gr,
scales = list(arrows = FALSE),
drape = TRUE, colorkey = TRUE,
screen = list(z = 30, x = -60))
i have two wireframes in one plot.
How could i change the color of the top - one to transparent (or only the grid).

Transparent colors OR two series on one histogram
Hi,
I want to be able to plot a single histogram of a measured trait with
trait values from two conditions on the same histogram to allow easy
comparison.
I have previously done this in excel by plotting the two series on a
single bargraph having calculated frequencies in bins. You then get one
condition plotted immediately to the right of the other. I hope that
makes sense?
I don't

image quality of plot inserted into PowerPoint
Dear R-helpers,
I need to insert an R (2.6.0) generated plot containing semi-transparent colors into PowerPoint (2002). When I directly paste it from the clipboard or insert it as (enhanced) Metafile (I'm on Windows XP) the semi-transparent colors don't show. When I insert it at as a Bmp, Png or Jpeg and then convert to PDF the semitransparent colors do show but the quality of the image

how to interpolate multidimensional (3D) spatial data
Hello,
I am an archaeologist who wonders wether a
multidimensional (3D) spatial interpolation
is possible in R.
The data consists of measurements in 3D space
with coordinates X-Y-Z and a measured variable
U, that is, U is measured at points located
at X-Y-Z.
e.g. a data structure like the following:
X Y Z U
5.10 5.02 16.03 6.674
5.41 4.32 14.03 6.668
1.72 3.59 12.28

transparency of one layer in multiple wireframe plot
Sorry sending this again - is anyone familiar with multiple transparent wireframe plots?
I already checked the ?wireframe, but with no examples and as newcommer its hard to find out a correct code.
If we set drape=F in the example:
g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2)
g$z <- log((g$x^g$g + g$y^2) * g$gr)
wireframe(z ~ x * y, data = g, groups = gr,

Maps and plotting
At our facility we have multiple sample points that are sampled on any
given day. What I would like to do is create a map of the facility with
the sample points (and point labels) and when we have out of
specification results, place a transparent dot over the area on the map.
As the number of OOS results builds up, I envision the dot getting
darker.
Are there any packages out there that can aid

R 2.0.0 is released
I've rolled up R-2.0.0.tar.gz a short while ago. This is a new version
with a number of new features. See below for the details.
As was the case with R 1.0.0, this new version represents a coming of
age more than a radical change to R. We do plan to celebrate the new
major version with press releases and such.
The release will be available from
