hi, when printing, image became black, and I got this: fixme:psdrv:PSDRV_CreateColor Colour is ff000000 i'm using wine 1.1.44, any idea how to fix this? thanks, angelo

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 want to display an arrow in the user interface between 2 GUI Components. I think I know how I can do it, but I ran into a problem displaying pixel images with transparent background. I describe this image display problem here and ask for advice. but if someone knows of a different and easier way to display arrows, please tell me. Example Problem: I want a FXHorizontalFrame to contain, from

Hi, In the example dataset below - how can I cahnge "gray20", to "blue" # data black <- rep(c("black","red"),10) gray <- rep(c("gray10","gray20"),10) black_gray <- data.frame(black,gray) # none of this desperate things works # replace(black_gray$gray, gray=="gray20","red") #

He everybody, Well I have a biplot CCA-like origined from plot.cca (vegan package). I need to rotate on y axis the lines and symbols of constrained and sites representation. If I do that on an image editor, I rotate everything, including titles, axes labels and positions. I just need to rotate the inner par and keep the variables names (constrained) and symbols in the new positions but with the

Hi, I'd like to use a custom color sequence (black - low values, green - high values) in am image() plot. While I can specify colors (say a sequence of grays) to the col argument, the ordering is getting messed up. I have two questions: 1. How can I get a sequence of say 256 colors starting from black and ending in green? 2. How is this specified to image() such that it uses the colors in

Is there a simple way to specify a theme or trellis (lattice) parameters so that, in a multipanel (conditioned) plot, there is no color and in the strips there is no shading? This is the effect achieved on page 124 of Deepayan Sarkar's "Lattice" (figure 7.2). I managed to trick lattice into making a grayscale plot on my interactive display as follows: > graphics.off() >

Has anyone an idea, how to force users to print b/w on a color printer. We are in the process to deploy color printers to some of our offices where they use centos 5.5 as their OS. They need the printers to print some advertisement material. But for everything else, they don't need it. And because of the costs of the color printing we would like to force them to use B/W where not explicitly

Hello, everyone! The code below allows me to produce the graph I want (I know - the colors are strange, but it's just for the sake of an example). After you run the plot<- part and then do print(plot) - that's what I want. However, when I run the bits of code below (with graphics devices) - what they print is different from the original plot. In .png, .emf, and .tiff - my dots change

Dear all, Could someone please explain to me how to convert color to black & white. For example: barplot(1:5,col = rainbow(5)) Because I need to print my plot to save my ink color printer. I don't want to convert to grayscale, but keep it as an RGB. I would be very happy if anyone could help me. Thank you very much in advance. Kindly regards, Muhammad Subianto

The gray (level) function returns different shades of gray, where level is a vector of numbers ranging from 0 to 1.? 0 is white and 1 is black and everything in between is a shade of gray. Is there a function that will let me choose two different colors?? For example, a 0 might be blue and 1 might be red and in between might be a mix. Jeffrey

Dear list, I am trying to plot a barchart (from lattice) in B & W, with 10 categories per bar. It seems that the colours are recycled after reachingcategory number 7, which creates a problem interpreting the chart. I therefore have two questions: 1) How do I get more shades? 2) Does anyone have a theme to share with me with distinctive shades in Black & White? Thankful for all the

Context: Windows XP, R 1.8.1 I'm studying Venables-Ripley "MASS" book and having a go at the many examples in library MASS. The code I'm checking (from script ch04.R) now is ...... data(swiss) splom(~ swiss, aspect = "fill", panel = function(x, y, ...) { panel.xyplot(x, y, ...); panel.loess(x, y, ...) } ) which produces an agreable plot with a gray

M. Camanm posted in Jul 1999 the following message: " Is there any way to fill the bars in a barplot() with solid lines for postscript output, i.e. cross hatch or parallel lines, or a halftone gray rather than (semi) continuous-tone gray produced by gray()? S allows this, or at least used to, via the angle and density arguments to barplot(). The objective of course, is to produce camera

OK, so this is a really stupid question and should be incredibly simple to do but I can't figure it out. So maybe someone would be so kind as to tell me. I have a vector of zeros and ones. I want to replace all of the zeros with "black" and all of the ones with "gray". That's it. Any help would be appreciated. Thanks, Paul `-:-. ,-;"`-:-. ,-;"`-:-.

Hi, I occasionally run out of color in my X11 terminal. At this point, R will issue this error message: Error: X11 cannot allocate additional graphics colors. Consider using colortype="pseudo.cube" or "gray". An immediate x11(colortype="pseudo.cube") doesn't work as the colortype seems to be shared among the different x11 plotting windows. So I have
