similar to: bitmap patterns in R fill

What is the simplest (namely: minimum number of libraries or conflicts) way to fill a polygon with a pattern? For example, suppose I have (in a graphic file, like a jpeg) the drawing of an "X". Then I fill a polygon (like a triangle) with this pattern, and get something like: X XXX XXXXX XXXXXXX (where the border "X"s could be truncated). I searched the rimage

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",

Hi All, I would like to fill the area under a curve with a gradient of colors. Are there any packages or trick I could use Thanks Stefan Stefan Van Dongen Antwerp [[alternative HTML version deleted]]

Hey all, I'm trying to create a plot of two semi-transparent regions. The reason they need to be partially transparent is so that I can see if there's any overlap. Here's some example code: # BEGIN pdf(file="test.pdf",version="1.4") plot(0,0,type="l",ylim=range(-3,3),xlim=range(-1,5)) polygon(c(0,1,2,3,4,3,2,1,0), c(0,1,2,1,0,-1,-2,-1,0),

Hello all, I'm using R1.2.2 and wonder whether there is already a new (unofficial) version that supports fill patterns for polygon(). thanks M.E. -- +------------------------------------------------------- | Marcus Eger +-------- ><> ------------------------------------------- | E-Mail: eger.m at gmx.de (NEW) | marcus.eger at physik.uni-marburg.de (OLD) | WWW:

hi, did'nt see anything in the archive: map('world',pro='rectangular',para=0) yields a strange artifact (horizontal bar) extending over the whole map at a certain latitude range (approx 65 deg. north), whereas map('world',pro='rectangular',para=180) (which should be the same) does not show the artifact. the artifact shows up in other projections as well,

Hi all, it there any possibility to draw colored shading lines of a polygon plot? E.g. plot(polygon_object,col="red",density=10,angle=45) produces only black shading lines within the polygon. With many thanks for any hint Albrecht

Hello, This is a usage question for others with experience of R under the Aqua Mac OS X interface. Basically, I don't succeed in importing PDF files (created with the 'Save As' menu to Quartz device windows) into Illustrator. Versions up to (and including?) 10 loose paths (lines/polygons) and or fill them in black. Version CS (11) on the Mac imports almost correctly, but, "to

Dear all, I would like to produce a map with information about the patenting activity in German districts, by coloring districts with different degrees of patenting activity in different colors. I work with the packages maptools, maps and spdep. The map data is read from an external .shp file (+ the corresponding .shx and .dbf files). Plotting a map with the IDs or the patenting indicator itself

Hi everyone, i've been trying to make a special plot with ggplot2, but I can't get it to fill the polygon I'd like to see filled so very very much. I want to display the difference or change in the distribution of the modified Rankin Scale between two groups. mRS is a scale for disability or daily activities competence. It looks like this.

Hi folks: Any idea when the density and angle arguments to polygon() are to be implemented? Or is there another way to achieve hatching fill patterns? TIA.

I have used polygon() to mark the confidence limits of a survival curve. In another project, I have used the col parameter to fill my boxplots. The poly() description refers to filling but actually produces hatching (i.e. lines ). boxplot() does truly fill the boxes with a colour or shades of grey (e.g. col="red"). My novices perception of R graphics is: If you can hatch it, you

M. Camanm posted in Jul 1999 the following message: " Is there any way to fill the bars in a barplot() with solid lines for postscript output, i.e. cross hatch or parallel lines, or a halftone gray rather than (semi) continuous-tone gray produced by gray()? S allows this, or at least used to, via the angle and density arguments to barplot(). The objective of course, is to produce camera

Hi, I wonder whether there is a way to generate a polygon (a triangle in my case) with color gradient using grid.polygon() in package grid? I tried something like library(grid) grid.polygon(x=c(0, 0.5, 1), y=c(0.5, 1, 0.5), gp=gpar(col=NA, fill=colorRampPalette(c("green", "lightgray"), space="Lab")(200))) But am only

I am trying to use the angle option in polygon to create polygons filled with horizontal and vertical lines. The polygons I am crating are irregular and it the angle function appears to set the angle of the shading perpendicular to the polygon sides rather than perpendicular to the axes. Is there any way to set the angle relative to the axes rather than relative to the polygon sides?

Dear list, are there any possibilities to fill a polygon with a point pattern or with a symbol pattern like '+' oder '-' instead of shading lines?

Hi to all, Here is a question which I cannot solve. Appreciate so much for any suggestions! I have a squared region which is irregularly divided into many rectangular patches. Each patch is associated with a value, and two patches possibly share a common value. I hope to fill in each patch a pattern according to its value. For instance, if a patch has value 1, then I fill in that patch

I want to plot many points and want to use circles. The filling color depends on variable a. if a=1, then not fill if a=2 then fill with red, if a=3 then fill with blue, if a=4, fill half with red and half with blue. Can anyone tell me how to plot the case "a=4"? Thanks a lot

Dear All, In the moment i'm using the map and maptools package to read shapefiles and display the maps. I'm looking for the possibility to draw points (randomly positioned or positioned according to a grid) into the polygons instead of filling the polygons with colors. For example: a map (shapefile) with 10 countries, 15 points in the polygon of country A, 20 points in the

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
