similar to: R plots pdf() does not allow spotcolors?

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

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

hi! I would like to produce simple black and white postscript figures for publishing. A black/white or grayscale or CMYK colormodel can be used, but not RGB colours. Can I produce postscript graphs in R that satisfy this? Following an earlier advice on the help-list I have tried using Photoshop to convert - but this seems to convert the vector format into raster format - giving larger,

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

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

Hi all: Since our designer friend Tuomas Kuosmanen (tigert) already did the hard work of specifying the CentOS logo colors in HEX, Pantone, and CMYK ... I did the small step of adding them to the wiki. This might be useful for you all to know it's now there: https://wiki.centos.org/ArtWork/Brand/Logo#logo-colors Also, I put a link back to the trademark guidelines for questions that are

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 all. A Journal we are sending an article to is asking for the following: To ensure the best reproduction quality of your figures we would appreciate high resolution files. All figures should preferably be in TIFF or EPS format... and should have the following resolution: Graph: 800 - 1200 DPI Photo: 400 - 800 DPI Color (only CMYK): 300 - 400 DPI (DPI = dots per inch) Since I am sending

A recent article in the earth science literature cited below and available at http://geography.uoregon.edu/datagraphics/EOS/ points out that rainbow color schemes and mixtures of green and yellow can be troublesome for people with color-deficient vision. The authors propose alternative schemes that can be viewed and downloaded in RGB, HSV, CMYK, and RGB256 formats from

Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous

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

Greetings all - happy new year, I''m having problems getting Pdf::Writer image insertion. pdf.image "/path/to/images/logo.jpg" is firing "JPEG marker not found!" Originally created the RGB (8 bit) JPEG in photoshop. After the above, I''ve exported with an alternate tool using (OSX) preview. This tutorial

The conversion of RGB to CMYK takes place in PostScriptSetCol() starting at line 2900 of R-2.7.0/src/library/grDevices/src/devPS.c if(strcmp(mm, "cmyk") == 0) { double c = 1.0-r, m=1.0-g, y=1.0-b, k=c; k = fmin2(k, m); k = fmin2(k, y); if(k == 1.0) c = m = y = 0.0; else {c /= (1.-k); m /= (1.-k); y /= (1.-k);} r, g, and b have already been normalized to the

The byte pixies have rolled up R-2.13.2.tar.gz at 9:00 this morning. This is intended to be the final release of the 2.13 series, for the benefit of those apprehensive of putting 2.14.x into production use. The run-in for 2.14.0 starts on Monday, with a planned release on Oct 31 (The Great Pumpkin Man Release). You can get it from http://cran.r-project.org/src/base/R-2/R-2.13.2.tar.gz or wait

As part of my GSoC project I have to work out a spec that covers how applications should communicate color management related properties between each other and the compositing manager. The main idea of the project is to let the compositing manager do the color management on behalf of the applications. But before that can happen, the applications have to tell the compositing manager how they want

Hello I looked on the archives but did not find answer for that... Running R CMD check for a package, i get an error: Error in parse(n = -1, file = file) : unexpected symbol at 3341: } But how can I find which file is guilty? What is this 3342 referring to? Finally the solution I found is to source() every file until I find the file where the problem is... Is there some better way to do it?

Hi My goal is to do a (multiple) regression, just knowing that my Y variables will be the say k first variables of a matrix/data frame. I thought I should do it with eval(parse)) but encounter a strange problem. See: lm(y~.-y, data=freeny) #that's what I want to do in the one equation case #Problem is I don't know name of the variable... only that it is the first one... #so idea is to

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))
