similar to: black and white colormodel for postscript figure

Hi We are about to publish a book, which contains figures made with R plots. An important detail that we did not take into account is that the book will not be printed in 4 colors (cmyk mode), but only 2 (black +"spotcolor"). The spotcolor we use is part of the big Pantone family. The problem is that both pdf() and postscript() offer either rgb or cmyk, but no spotcolors such as

I'm trying to create figures in PDF that use the 'gray' colormodel instead of the default 'RGB' model, by requirements of a publisher. My problem has to do with the fact that I'm not being able to get gray colors with this option on the pdf() driver. Here is a small example for problem replication: > R.version _ platform

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

dear R experts---I am struggling with the requirements to prepare my files for my printers. I am printing in 2/2 format, which means cyan and black for me, which they take from my color-separated pdf files. R comes into play, because it produces all the figures that are embedded in my book (pdflatex). now, TeX has no problems producing CMYK files. However, R produces RGB files (for

I have made some modifications to the X11 graphics driver so that it is more flexible about its use of colors. I have added a new parameter to the X11/x11 function which controls this. The parameter is currently called "colormodel" and works as follows: colormodel = 0 Monochrome graphics colormodel = 1 Grayscale (256 shades) colormodel = 2 Pseudocolor1 colormodel = 3

Please do study the FAQ and posting guide: R 2.7.0 is not the current sources, and this was changed a month ago in R-devel. You were asked to check for such changes before submitting a report. Also, there is no unique way to do undercover removal in conversion to CMYK, and so it is wrong to call any method 'wrong' -- in fact the one used in earlier versions of R was a documented

My goal is to create a graph with one column and three rows into a single graphic. The mfrow, mfcol, and layout functions all have the same effect: three graphs are produced in a single pdf file, having one graph per page. This is not what I want (I didn't want multiple pages). Just before I sent this post, I was able to generate the desired output with split.screen. Is this the expected

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

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() >

To be precise: Black lines were black, but pale gray areas were an

Hello all, I suspect my problem is not new: I am having difficulty getting an alpha character to print in a PostScript file made by R graphics (in my legend). At first, I figured out how to actually get the character on the screen; however, when I saved the graphic to a PostScript file the alpha character was replaced by "..". Obviously, something is not working when encoding.

Hi. This post follows on from: http://lists.xensource.com/archives/html/xen-devel/2005-04/msg00185.html And is possibly related to the bug referenced here: http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4335360 In summary: Java processes are doing odd things. 1) It appears that number values are mysteriously changing. e.g. if you look at the Hashtable error there is no way the

Dear Erich and John, thankyou for providing RColorBrewer! Are you working on options for CMYK or RGB return values? Thanks again, Darren [[alternative HTML version deleted]]

Hello, I have an example of a 2 paneled plot, with two different aspect ratios displayed on one page. An example would help n=20 x1 <- cumsum(runif(n)) x2 <- cumsum(runif(n)) d <- data.frame(val=c(x1,x2),id=c(1:n,1:n), nt=c(rep("A",n),rep("B",n))) u1 <- xyplot(val~id | nt, data=d,aspect=1,layout=c(1,2)) u2 <- xyplot(val~id|nt, data=d,aspect=0.5,layout=c(1,2))
