similar to: Using dates on axis with Grid plots

I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis()

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.)

When I use grid.rect to print a multi-coloured grid, it is incredibly slow compared to a single colour grid, or even a two colour grid. I've set out some simplified examples below. This is something I run literally thousands of times a day, so I would greatly appreciate any hints on how I might improve the speed??? library(grid) pushViewport(viewport( width = unit(100,

I have a stupid problem that is currently driving me crazy... Let us suppose that I want to draw a big red square in the middle of my current device (say X11) I tried the following code : pushViewport(viewport(xscale=c(0,1), yscale=c(0,1)), just=c("center", "center")) vp1 <- viewport(x=unit(0.5, "native"), y=unit(0.5, "native"), width=unit(0.4,

Oh Knowledgeable Ones: I'm working on a project using grid graphics (for the first time). A toy example is given below, run it simply with >foobar() I am wondering why the pink dot and concentric circles are not centered on the 3-color axis system. Further, I feel like the concentric circles don't have the intended radius - if my math is right, the outmost circle should touch the

Hi, I m working on R and read one image with russian font using readjpeg() function and write it on pdf (using grid). But russian text is not visible on pdf. How can i fix my pblm?

Hi, I have an array of 2d node locations and an array triangles, and would like to plot something like a image or persp. An example of doing it with rgl is: library(ncdf) library(rgl) # wget http://www.maplepark.com/~drf5n/extras/teapot.nc teapot<-open.ncdf("teapot.nc") z<-get.var.ncdf(teapot,"tris") l<-get.var.ncdf(teapot,"locations")

Dr Murrell and others, It seems grid.ls() fails after any use of grid.remove(). It gives an infinite recursion error even in the simplest cases, and no matter what arguments are passed to grid.ls. > library(grid) > grid.newpage() > grid.lines(name="foo") > grid.ls() foo > grid.remove("foo") > grid.ls() Error: evaluation nested too deeply: infinite recursion

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))

In the example R script below, horizontal gray gridlines are drawn at y coordinates where the points are drawn with the code: panel.abline(h=y, v=xScale, col.line="gray") How do I change this so that the horizontal gray gridlines are drawn at y coordinates where the y labels are drawn? The challenge is that each panel has different y-ranges (in my real example the y-ranges and

Hello, I'm trying to follow the documentation of how to use gridBase, and I've reached the minimal code example below as my best effort. Can someone explain how to keep the column of boxplots on the same page as the rectangles (even though I've tried new = TRUE) ? Also, would it be hard / possible to match up the middle of each boxplot to the middle of each rectangle ?

Dear r-help I draw plots with xyplot() function. Each plot contains also a line of regression. I want to write the trend value and its significance (obtained with lm()) below each panel. I use ltext() for this. But the text is cut, when it comes outside a panel. Moreover (obviously), it doesn't appear at all when its coordinates are outside a panel. Could you,

Dear list, Can someone explain why the childNames below gives character(0) instead of the (canonical) names of the children grobs of the xaxis gTree ? [1] "major" "ticks" "labels" Many thanks in advance, Tobias ### minimal example code ### library(grid) pushViewport(plotViewport(c(5,4,4,2))) pushViewport(dataViewport(1:5, 1:5)) grid.points(1:5, 1:5)

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

Hello, I plotted a nice tree with "ctree" . It shows 3 nodes with the prediction of my 2 groups. (see picture) Unfortunately I need a larger scale to read the exact prediction of my groups to get the specificity and sensitivity. I tried to change the scale with "axis" but it didn't work, my guess because it's not a normal graph with x and y axis. Has someone an idea

I am having a problem in editing a grob. It works ok if I try to shift the grob using npc coordinates but if I do the same thing using native coordinates the grob disappears. What is wrong? library(grid) grid.newpage() # create viewport pushViewport(viewport(xscale = c(100,200), name = "X")) # draw vertical line grid.lines(150, 0:1, default.units = "native", name =

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 R list members, I'd like to produce rug plots at the bottom of panels in a trellis display (using the lattice package), but par("usr") doesn't return user coordinates for panels, and consequently rug fails, as the following example (suggested to me by Georges Monette) illustrates: > x <- rnorm(50) > y <- rnorm(50) > f <-

Dear Rxperts, How do I hide the top and right axes in multiple panel plots? A couple of examples are provided below..
