Dear all, In an attempt to draw fill patterns in grid graphics, I have encountered a behavior of grobX that I cannot understand from the documentation. Consider this, library(grid) ## gTree g1 <- gTree(children=gList( rectGrob(0.5,0.5, width=unit(0.8,"npc"), height=unit(2,"cm")), circleGrob(r=0.3)), vp=viewport(0.5,0.5)) ## gL...

Hi there, I just wonder how to draw this kind of picture... http://www.nabble.com/file/p24158796/b.jpg http://www.nabble.com/file/p24158796/a.jpg and this is what i have done %%%%% library(shape) library(diagram) curve(sin(x),bty="n",-8,8,yaxt="n",ylab="",xaxt="n",type="n",xlab="") axis(1,labels=F,at=seq(-8,8,1))

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

Hello, When I use savePlot(filename="xy",type="eps") or savePlot(filename="xy",type="wmf") , I get the following error: Error in grid.Call("L_textBounds", as.graphicsAnnot(x$label), x$x, x$y, : Polygon edge not found (zero-width or zero-height?) This doesn't occur when I change the type to "jpeg" or "bmp". Can

Hi, Am looking for an R package that will provide the drawing of curves and arcs of arbitrary shapes to use in illustrations. For example bent lines and arrows. Allan.

Hi Folks, I'm wondering if there are people out there who would be interested in what would be involved in developing an interface between R graphics and the 'pic' language. Explanation; 'pic' has been part of the Unix 'troff' typesetting suite since very early days (1970s), and also of the GNU troff: 'groff'. Its function is to act as a preprocessor,
