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, dt$A) # regular plot... densityplot(~y|B, groups=A, data=dt, plot.points="rug") # the actual panel... panel.de...

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: # dummy data factor<-rep(c("Alice","Jone","Mike"),e...

3D density plot of point set
...and where I might find the respective docu then I would already be very thankful. I have a large set (a few million) of points in 3D. I would like to create 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 Lutz

How to use alpha transparency channel for colors?
...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 'alpha' to the function col2rgb() provides the ability to return the alpha component of colours (as well as the red, green, and blue components). I'm using R 2.0.0 on Windows 2000 and wanted to try this feature. The following simple test works fine:...

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??? library(grid) pushViewport(viewport( width = unit(100,

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
...(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 is not good enough when I zoom in at say 300% (I'm making a poster for a meeting so being able to scale up is crucial) Any suggestions? You can download the PDF file containing the four images corresponding to the original Png, emf, Bmp, and J...

how to interpolate multidimensional (3D) spatial data
...e distance or something like this. Having done 3D kernel density estimation I think of a visualization of the interpolated 3D field of U like the density in 3D rgl-plots {function 'plot(kde(xyz,hpi(xyz)))', package="ks"}, that is, having the interpolated values shown as a kind of semitransparent cloud in 3D with the colour and/or the transparency representing the values of U. Is there any function or package that does this kind of computation and visualization? Please excuse my bumpy English. Thank You for any help. And, thanks to the volunteer moderators allowing mails for non-subs...

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
