Hello R community, I am hoping to use a new package that I just installed called "grImport" to import ps images into R for further manipulation using either base graphics or grid. I downloaded the most recent version of Ghostscript from http://www.cs.wisc.edu/~ghost/ that I could find (v.8.56) for Mac OSX. However, I am apparently quite ignorant about how the required

I couldn't run PostScriptTrace() from the package "grImport" without an error. At first the postscript program couldn't be found. however the problem persisted after the full path the postscript program was indicated. I read earlier post on the subject in vain. See the codes and output below. The file "Senegal_location_map.ps" was originally a "svg" file from:

Dear list, I have two questions regarding grid.symbols() in the grImport package. This package allows you to import a vector graphic in R, and grid.symbols() can be used to plot the resulting glyph at arbitrary locations in a grid viewport. I have tried the code in the grImport vignette, which is most interesting, however I am stuck with two problems: 1- Is there a possibility to create a

Hello, I am trying to import an .eps file created with Adobe Illustrator and plot it in a Quartz window (I am using R 2.11.1 GUI 1.34 Leopard build 32-bit (5589) on MacOSx.5.8). I thought of using the PostScriptTrace() to convert my .eps file to RGML, and then use readPicture to plot the file, but the first step already fails (cf below). I also had a look at the add.image( ) example,

Hi, using too long pathnames for bitmap() crash R on WinXP. I've verified that this is the case with R version 2.4.1 Patched (2007-03-25 r40958) and R version 2.5.0 alpha (2007-03-30 r40957). I cannot reproduce it on Linux. REPRODUCIBLE EXAMPLE: % Rterm --vanilla # Tell R where Ghostscript is gsexe <- "C:/gs/gs8.54/bin/gswin32c.exe"; gsexe <- "C:/Program

Hi, in help("R_GSCMD") it says "R_GSCMD: Optional. The path to Ghostscript, used by dev2bitmap, bitmap and embedFonts. Consulted when those functions are invoked.". However, if 'R_GSCMD' contains a full pathname to the Ghostscript executable (as above "path" indicates), e.g. > Sys.getenv("R_GSCMD") [1] "C:\\Program

Hello, R users. I am trying to embed Computer modern fonts to an R plot and I get the following error. CM <- Type1Font("CM", + c(paste("cm-lgc/fonts/afm/public/cm-lgc/", + c("fcmr8a.afm", "fcmb8a.afm", "fcmri8a.afm", "fcmbi8a.afm"), sep=""), + "./cmsyase.afm")) > pdf("cm.pdf",

A colleague designed a script for a bar plot, which I'd like to export to my directory via the barplot command: bitmap(file="barplot.tif", type="tifflzw", height=4, width=6.5, res=1250) Unfortunately, this command produces the following error message: Error in system(paste(gsexe, "-help"), intern = TRUE, invisible = TRUE) : 'gswin32c.exe' not found

Hi, I've installed several versions of R on a number of Window systems. I get the following error message (which I don't get on linux) > dev2bitmap(file="test.jpeg",type="jpeg") Error in system(paste(gsexe, "-help"), intern = TRUE, invisible = TRUE) : gswin32c.exe not found Any idea how to fix this? It seems common to all windows systems

Hi All I still have a problem with ?bitmap? function in R, I have downloaded ghostscript 8.71 and added the path to the executable to the path environment variable, by going to the control panel , system, advanced system settings, added C:\Program Files(x86)\gs\gs8.71\bin to the path variable. I have also added the R executable path to the path variable. I have a 64 bit computer with windows 7

Hi, On windows I'd like to run a batchfile that leaves me a plot. As a test I have the scriptfile "test.r" which only contains: x <- 1:10; y <- sample( 10 ) plot( x, y ) Now I tried the following (but nothing worked): a) "R --vanilla < test.r" in the cmd window, => that doesn't give me a plot b) the same, but I added

Hi, I am having trouble saving graphics from R. jpeg() saves a file with the correct name to the correct directory, but it consists of a blank (white) jpeg with the specified dimensions--the image itself is not being saved. My code is jpeg(filename="myfile.jpg", height = 2.5, width = 8, units = "in", res = 72, pointsize = 12, quality = 100, bg = "white",

Hi, I'd like to fill an existing svg (or png) map with gradient colors. In detail: The file http://commons.wikimedia.org/wiki/File:Karte_%C3%96sterreich_Bundesl%C3%A4nder.svg should be filled with the population density data from this table: http://de.wikipedia.org/wiki/%C3%96sterreich#Verwaltungsgliederung choosing the right color saturation (or whatever). The final result should be something

I am using tools::compactPDF for reducing the size of some pdf-files with GhostScript. I had some trouble in the beginning as the documentation seems not to match the usage of the function. For GhostScript, one has to set the argument gs_cmd, which has the following description: gs_cmd - Character string giving the path to the GhostScript executable, if that is to be used. On Windows this is

Hi… I want to use grImport to create a watermark on a plot() using the methods Paul Murrell describes here: http://cran.r-project.org/web/packages/grImport/vignettes/import.pdf (page 28). I can essentially reproduce this manually at the R prompt, and independently I can use grid.picture(…) successfully in a R script, but when I attempt to do do this in my script: • • •

I am trying to add a copyright disclaimer outside the plot borders of some images I have created. I can use mtext() to add the written portion, but I would like to have the Creative Commons license image (http://en.wikipedia.org/wiki/File:Cc.logo.circle.svg) before the text. I've found that I can plot a .png image inside the plot boundaries using rasterImage() but I can't figure out how to

Hi everyone I'd like to flip grobs (grid graphical objects) along an axis, e.g. flip grobs horizontally or vertically. I couldn't find any hints, neither in the documentation nor by searching the web. Does anybody know how to achieve this? Cheers /thomas

Dear helpers, I'm trying out the embedFonts() to embed fonts into my pdf files. However, when I inspect the new pdf with a program designed to look for embedded fonts, I see that the fonts have in fact not been embedded. Below are my calls.

I'd like to paste a zodiac sign on a graph, but it only prints it when I add another unicode ( \u3030) to the desired \u2648 - why? See the examplecode (compare the orange with the skyblue): plot(c(-1,1),c(-4,-2),type="n") text(x=0,y=-3.0,labels="\u2648 \u3030",cex=2.3,col="skyblue") text(x=0,y=-3.2,labels="\u2648",cex=2.3,col="orange")

Many medical journals and publishers require that images, whether photographs or line art, be submitted as high resolution .TIFF images. One option for R users is to produce an image in one format and to convert it to a .TIFF file using a second software program. My experience has been that this option often results in images of poorer quality, often with blurry contours, and a loss of
