Hi, I'm looking the best way to fill irregular polygons with patterns, Something like the function grid.pattern do, but my case is with irregular polygons. Whit this script I can get it, but I'm looking for an "elegant" solution.. library(grid) grid.polygon(x=c(0.2, 0.8, 0.6, 0.6, 0.8, 0.2), y=c(0.2, 0.2, 0.3, 0.5, 0.7,0.7), gp=gpar(fill="grey",

Thanks - it is indeed the first '.' that's the problem...

Hi, I've got a quick question about file permissions and packages... I'm creating my own package, and am having problems with its vignette not being seen when I install it into R... As I understand it, the permissions of the source tree should be as follows: o Directories - drwxrwxr-- o Files - -rw-r--r-- Everything builds and runs through 'R CMD check' fine with

Hi, Forgive a very basic question... I need to take two lists-of-lists, and apply a function to each pair of elements in the lists to return a single list... For example l1 <- list(1:5,6:10,2:15) l2 <- list(1:8,4:12,1:19,4:20) I could easily do an lapply across each of them, but is there a function that does a sort-of pairwise-apply across both together? Does anybody know of a good

This was actually the first thing that ChatGPT debugged for me. The issue was that I was able to click on the link when I displayed the raw SVG in the browser (you can use that to test whether the syntax is even correct), but not when the svg displays inside a html page with the <img ...> tag. ChatGPT correctly identified the issue and suggested a solution using <object ...> tags

Since now many browsers support (ECMA/Java-)scripted SVG, I am wondering whether there are already any examples of inserting R code into SVG documents (or a Javascript canvas?) either directly, or perhaps more likely through a JavaScript layer, to dynamically generate graphics or make them interactive? I am aware of the excellent packages gridSVG and SVGAnnotation, which facilitate making

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

Dear all, is there a good way to create SVG plots with R whose elements have titles (tooltips) or act as hyperlinks? I am using the RSvgDevice package, which works great - but it doesn't seem to support the notion that plot objects have titles or are act as hyperlinks, so I am helping myself by giving the objects funny unique colors and then postprocessing the .svg file. I wonder

Hi everybody :) I use R to plot things in svg format. One of the things is text, of course. I noticed that text() in svg() gets saved as path, which is unacceptable for my purposes. (Interestingly, text() in cairo_pdf() gets saved as text.) Is there a way to save text as text in svg? And paths also is what I plot a lot. I know there is segments(), which plots disconnected segments, and things

Hi! When inserting R plots into a document using odfWeave, I fought for a while to get Lattice plots use the same text size as base plots. I eventually discovered that specifying a point size via e.g. svg(pointsize=10) has no effect on Lattice plots. One needs to adjust the size manually via: trellis.par.set(fontsize=list(text=10, points=8)) This is also developed for both Lattice and ggplot2 by

Hi all,I would like to draw a simple circle where the color gradient follows the rule color = 1/(r^2) where r is the distance from the circle. I would also like to add a color bar with values going from -40 to -110 (and associate those with the color gradient that fills the circle). So far I experiemented with draw circle

I am trying to use the RSvgDevice package to produce some SVG graphs which I want to edit with Inkscape 0.42. Under Linux (Kubuntu 5.04) I use the following: library(RSvgDevice) plot(1:10, 1:10) devSVG(file = "/home/adi/Rplots.svg", width = 10, height = 8, bg = "white", fg = "black", onefile=TRUE, xmlHeader=TRUE) but when I tried to load the file into Inkscape it

Hello all, I'm trying to write a function that produces a main plotting region with several square plots along the right side. Ideally the size of right side plots will scale only with the height of the entire plot, yet never overlap with another secondary plot. The following two snippets get close, however, as I resize the plot horizontally the right side plots (green squares) get smaller

The following code, though not brilliant, works on an A4 page. It might look odd on other devices of a very different size. =============X8------- cut here ---------------------------- require(grid) wide <- 15 vps <- grid.layout(nrow = 3, ncol = 4, widths = unit(rep(1, 4), rep("null", 4)), heights = unit(c(99, 1, 99),

Dear list, I'm puzzled by the graphical output in the following example, library(grid) foo <- function(){ grid.rect(gp=gpar(fill="black")) print(get.gpar()$fill) grid.rect(width=0.2,height=0.2) } png("test.png", bg = "transparent") foo() dev.off() png("test1.png", bg = "white") foo() dev.off() It seems that the default value of

Hi all I want to draw a graph containing points and edges. Package graphics could do this. However I want to make each those points and edges clickable with a hyperlink on them. Anybody know how to do this? Thanks very much.

Hi R-users and R-experts: Is it posible to make transparent graphics on R? I mean, one graphic with colors over another one but both visible with transparent options? Thank you for your help Kenneth --

Hello all, I'm trying to write a function using the gridBase package. I'd like to push several base subplots to a larger plot constructed with grid. However, I'm having trouble getting consistent results when running the function when the plotting window (quartz) is closed, when it is left open and the plot function is repeated to the same window, and when the output is saved to a

Hi, I want to produce two parallel rotated strips with color gradient. So far, the sample strip is something produced by this: pushViewport(viewport(x = unit(0.638, "npc"), y =unit(0.386, "npc"), width=.62, height=0.006, angle=137.2)) grid.rect(y=100:1/100, just="top", gp=gpar(col=NA, fill=colorRampPalette(c("lightgray",

Hi everybody, I just notice a strange behaviour of gpar's fill argument when using non-postscript devices: The default of the argument is transparent (according to get.gpar("fill")). So as expected, the following code draws a nice red rectangle in the middle of my X11 or postscript device. pushViewport(viewport(width=0.5, height=0.5)) grid.rect(gp=gpar(fill="red"))
