similar to: graph shading is overlaying axes

Please see this code for a demonstration of my problem... xlim <- c(-1,5) plot(1:4, xlim=xlim) abline(v=xlim[1]) abline(v=xlim[2]) When I refer to xlim, it is not referring to the boundaries of the graphical region, it refers to the maximum and minimum xticks. My question is how can I refer to the x axis boundaries (and similarly y axis) of the graph? -- View this message in context:

Am just feeling my way into the grid library, and cannot figure out how to define the plot limits. 3/5 of the example polygons below plot in the default 0-1 range viewport. But when I try to redefine the viewport the polygons plot in the same places. I also get the same result without employing push/pop. (As you can see from the scale I'm trying to introduce, I want to plot map polygons.)

Dear all, I feel like I've been reinventing the wheel with this code (implementing type = 'b' for Grid graphics), http://econum.umh.ac.be/rwiki/doku.php?id=tips:graphics-grid:linesandpointsgrob Has anyone here attempted this with success before? I found suggestions of overlapping large white points to mask the lines but it's not ideal. I welcome any comments on the code.

Ok, now we have the mapping of color names to color codes (see below) and conversion to rgb (something like Ben Bolker's function), but how to convert rgb to hsv? Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker Details below Regards Jens etc/colors.big maps 455 names to rgb in S syntax etc/rgb.txt maps 657 names to rgb in C syntax, but unlike colors() it has mixed upper and

Is there a way to make a shading interpolation on an image plot? Something similar to matlab 'shading interp', I think it is called Gouraud shading. What I want is to make a image plot look nicer. with image() it looks very facetted, and I would like to make it look smoother. I've tried with interp.surface() in fields package but it (obviously) makes nan values at the borders and

All, The code below produces a color 3D graph. I'd like to make it black and white shading. I tried setting col.regions to FALSE but this just made it completely white. I want the graph to look exactly as is, except black (or grey) and white shading. Is this possible? Cheers, David p.list = c(.01, .1, .25, .5, .75, .9) cov.list = c(.2, .1, .05) ### leave out .01 X = rep(p.list, 3)

Dear all, might there be a modified barplot function out there which allows the user to specify a fill color for the bars and independent parameters for the overlaid shading lines ? Currently, when I specify density and col, the fill color for the bars is white. Thanks! Markus [[alternative HTML version deleted]]

I am stuck at the following problem. I have two moving averages. One is faster than another. After plotting them I need to shade area between them in green when the faster is above slower and red where faster is below slower. Something like this: http://charts.stocktwits.com/production/original_9205513.png?1345576091 I tried with polygon but I can't do it. Any hints? Regards olo -- View

Dear All: I am trying to shade the area between the two lines; *line 1* and *line 2*. You can use this code as an example. x100<-c(-1,1,2,3,4,5,6,3) y100<-c(4,5,3,1,4,4,2,-1) plot(x100,y100) *##### line1* abline(a=-(Beta0-1)/Beta[1,2], b=-Beta[1,1]/Beta[1,2], lwd = 3, col="skyblue", lty=3) ##### lty=3, *##### line 2* abline(a=-(Beta0+1)/Beta[1,2],

Hi all. New to the list, so my apologies, if I am out of line. I was told, that window shading (rolling them up into the title bar) is on the TODO-list. As I normally rely heavily on this feature, I just wondered which priority it has, i.e. when I can expect it. I rely solely on your kindness for this, as I am neither versed in C nor graphical effects, and thus cannot provide code of my own.

My thanks still stands, however, when one reloads compiz, any shaded windows are closed. Just wanted to let you know Best regards, Sune M?lgaard -- The best way to accelerate a Macintosh is at 9.8m sec sec. - Marcus Dolengo

If I update to the latest CVS, my window decorations disappear. I'm running Gnome 2.15.2 under Gentoo, so it's possible this is some interaction with the newest gtk+ or other Gnome libraries. Gnome-window-decorator is running and the decoration plugin is loaded. I first had this problem with the latest quinnstorm, so I switched to the latest CVS for fdo compiz, removing

Hi All, Sorry to bother all of you. Currently I am developing OpenGL Shading Language (GLSL) front end as an hobby. Like clang it will generate LLVM IR. I have modified the ucc front end ( http://ucc.sourceforge.net/) to support GLSL language. The parser of ucc is hand written and seems pretty fast. Currently 70-80% work I have completed. I will appreciate your feedbacks and I will be very thank

Hello All, Thank you in advance. I have looked up and down in the archives to see if I could find some help on moving the polygons to the background of a ts.plot. I've tried panel.first in the gpars(...) arguments and trellis.focus, but I get errors. Am I missing something easy here? Here is my script: ts.plot(tsdjia, tstenyield, gpars = list(xlab = " ", ylab = " ",

Hi, I have a contour plot and I want to shade a polygon (the area below a line) but the polygon shading wipes out the contour lines. Does anybody know how to shade the polygon and still see the contour lines? Thanks. Jeff

Hi there, I'm having trouble working out how to change the colors of polygon shading lines. If I plot a polygon with polygon(poly,density=30,borders=gray(0.5)) I get gray borders but black shading lines; I have tried adding col=gray(0.5), bg=gray(0.5) and fg=gray(0.5), but no luck. How can I change the colors of the shading? The help file doesn't seem to detail this, so any

Hi, I've got the following edf: *** x = c(1.6,1.8,2.4,2.7,2.9,3.3,3.4,3.4,4,5.2) F2.5 <- ecdf(x) plot(F2.5, verticals= TRUE, do.p = TRUE, lwd=3, ylab = "", xlab = "", xlim = c(1,5.5)) abline(h= (0:5)*0.2) #mean abline(v=mean(x), lwd=2) mtext(text=expression(bar(x) == 3.07), side=1, adj=0.462, padj=3, cex=1) *** Now I would like to

Hi, I have a graph with seven parallel horizontal lines. Is it possible to shade the area between two adjacent lines? Thank you in advance, Hannu

Dear R-Community, I have the following problem and was wondering whether someone could help me out. I have a number of time series of discharge (up to 3000 data points in some cases) which I would like to compare on the same line plot by shading the area between some of them. Can anyone tell me how to do that? I have tried to fiddle around with the polygon function, but the curves interact a
