...;W theme ltheme$strip.background$col <- "transparent" ## change strip bg lattice.options(default.theme = ltheme) ## set as default --8<---------------cut here---------------end--------------->8--- Is there a simple way of achieving something in between these settings (using grayscales for the default colors)? Thankful for any pointers, Patrick

I'm working with the following code below to generate a how do I set the h,c, and l values such that the significant, positive residuals appear different on a grayscale printer from significant grayscale residuals. The challenge as I see it is that one can only distinguish the positive and negative residuals with the hue/. Varying the chroma and the luminance only affect the

I have an HP Photosmart C3180 All-in-one. As I haven't had any need for color lately, when I last replaced ink, I only replaced the black cartridge. It didn't work, even when printing grayscale-only images, even when telling print-set-up grayscale-only. Is there a way to tell my printer to use only the black ink cartridge. My test image is a handmade postscript file that only use setgray

I need grayscale formatting for a wireframe. The only col.regions that I can find are color palettes are all colored: rainbow(n, s = 1, v = 1, start = 0, end = max(1,n - 1)/n, gamma = 1, alpha = 1) heat.colors(n, alpha = 1) terrain.colors(n, alpha = 1) topo.colors(n, alpha = 1) cm.colors(n, alpha = 1) The code follows: X11() library(lattice) par(family="serif", cex=1.2)

Dear list, I am sorry if this is a FAQ, but I have just started using odfWeave for report construction and it seems not to behave exactly like Sweave. I want to get my figures in grayscale, but the tip given in the FAQ of Sweave http://www.stat.uni-muenchen.de/~leisch/Sweave/FAQ.html#x1-10000A.8 only produces gray scale images in the screen output, not in the odf document. This is my init code:

Hi all. It's been a long time since I wrote to this list. Glad to see the R project well and working. I am working with a 3D plot similar to this: http://old.nabble.com/file/p26525177/rgl-device.png rgl-device.png The underlying picture is a JPEG image, loaded with the rimage package and coerced to the matrix. Spheres denote control points, collected from this picture and must be

Dear all, When making a plot with the command plot(xVector, yVector), there are many points that collide on the same place in the plot. In order to make this plot clearer, I have been looking for a way to colour the points based on the number of points that fall onto each other. If only one point falls on a particular location, make it gray, if many points fall, make it black. I tried to search

Hello, First of all my thanks to everyone for their suggestions. I'm still having an issue getting this network printer going. I'm now getting a windows error from explorer.exe, i've checked all the windows system, application, and security logs and of course the error is not in them. I then turned samba's debug level to 10, reloaded it and tried again to access the printer. This

Is there a grayscale equivalent to alpha levels in rgb? Example: I have the following to make red transparent circles overlap with previously plotted blue symbols. symbols(x=sites$long,y=sites$lat,circles=log(sites$prop.nem +1),add=T,inches=F,bg=rgb(red=1,green=0,blue=0, alpha=0.5),fg=rgb(red=1,green=0,blue=0, alpha=0.5)) I'm having a hard time coming up with a grayscale equivalent.

Hello everyone, I am currently using the mvpart package and would like to change the color scheme it uses, and was hoping someone could help me out. All of the papers I have found have used a grayscale but I can't seem to figure out how they did that! Currently, mvpart plots barplots in a repeating sequence of 3 shades of blue. So if you have 6 response variables the same shade of blue is used

Dear all I prepared some image processing routine which depended on package ReadImages. Basically I imported image to R, changed rgb to grayscale, normalised an image made some selections and changed to image by imagematrix. Recently I learned that this package was removed from CRAN and can not be used in R 3.0.0. What options I have now to import image to R, change it to grayscale, make some

Hi, On my NV18 based laptop I experience artifacts related to text (however, 2D performance is really great these days): - With grayscale AA text is sometimes missing, often visible on the XFCE desktop - With subpixel (rgb) AA, even non-text related occur (icons are misrendered, ...) I've reported the issues here: https://bugs.freedesktop.org/show_bug.cgi?id=81283 With noaccel it works

Well, I wasn't really awake I guess.. It's just a script that calls GhostScript for pdf generation.. But the question still stands, what IS the best quality printer driver to use for GhostScript -> pdf printing? We need both colours and high resolution.. ------------------------ Hiya! Can anybody recommend what the best Windows XP printer driver is to generate pdf documents with

I could use some advice regarding xyplot. I've got 2 time series. Both cover approximately the same period of time (ie, 1940 to 2009). But one series has annual data and the other has monthly data. One refers to university enrollment; the other to unemployment rates. Both are currently in the same data frame. I'd like to use the monthly times series as a light grayscale background for a
