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 po...

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 whe...

Hi All: I've been struggling for a while trying to get grImport up and running. I'm on a Windows 7 (home premium 64 bit) machine running R-2.12.2 along with GPL Ghostscript 9.01. I've set my Windows PATH variable to point to the Ghostscript \bin and \lib directories, and I've created the R_GSCMD environment variable pointing to gswin32c.exe. I don...

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 Ghost...

How can I insert a vector image in svg or pdf format into a plot. Basically i need the equivalent of what the 'pixmap' package does for bitmap images. Cheers, Will Morris

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 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 origina...

Hi useR's, I have an image plot I want to overlay a map of the United States on, via map('usa'). The image is basically a large rectangular of various colors. When I overlay the United States map, the full rectangle of the image plot is visible, but I only want to display the image WITHIN the United States boundary. Does anyone know a way to do this? Thanks in advance, dxc13 --

Hello, I want to place two plots on top of each other. However, the problem is that I can't figure out a simple way to align them correctly. Is there a way to specify this? Since the data is bunch of coordinates and the second layer is an outline of a map (a .ps file I import using the grImport package), I suppose one option would be to specify a set of "artificial" coordinates that make up the very corners of that plot, and then have the second layer will this same space. Any ideas how to do this? //John

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 useRs, I generated a simple image-based report using the sequence: pdf(....) plot(.....) textplot( for short texts, from gplots) dev.off() Is there an easy way to include an single pdf-page from an external file (not R generated). Note: For final reports, I know how to use Sweave, but I am looking for a quick solution with less overhead. Something like textplot() for pdf. Dieter

Hello Everybody, I have an eps figure an awesome bacteria and a plot (generated using R) also in eps format. Now it looks like there is space for only one figure and I have to insert the picture of the bacteria into the plot. Is there a way to insert figures (eps/png/jpg) in to plots (may be control over placement of figures in the plot as well?) ? By plots I mean data represented using axes and

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

Is it possible to add lines or other user defined graphics to a plot in R that does not depend on the user scale for the plot? For example I have a plot plot(x,y) and I want to add some graphic that is scaled in inches or cm but I do not want the graphic to change when the x-y scales are changed - like a thermometer, scale bar or other symbol - How does one do this? I want to build my own

Dear useRs: Is there a way to include a raster image (e.g., .gif, .jpg, .bmp) representing a company logo, a school logo, etc. into an R graphic? For example, it would be nice to be able to include the logo of the school into the charts that a student produces for her dissertation. Similarly, while working on a competitive analysis, it would be nice to be able to replace the names of the

Hello, I am plotting data as a venn diagram but would like to be able to control how it is plotted like a lattice object. Right now, it plots right away. I would like to name it and then plot at will. I thought to convert the whole thing to a PostScript file then get it back into R via grImport, but surely (please!) there must be a less roundabout way to do this. Any help is appreciated. Here is my code: # Wrapper function to draw Venn diagram Venn2 <- function(set1, set2, names, title,...){ stopifnot( length(names) == 2) # Form universe as union of both sets universe <- so...

Hi everybody! Is there any way to read a postscrit file into R? All the best to you Ralf Finne SYH University of Applied Sciences Vasa Finland

Hi, Is there a way to parse a postscript (*.ps) file with R (or perhaps with some other command-line utility)? E.g., I have a map in postscript format with lots of features, but I just want to extract the coastline and it's coordinates. Any help very much appreciated! Cheers!
