grumble, grumble, MS does not have llabs() llabs() is not defined in Visual Studio, however, _abs64() is. But if I switch to _abs64() the linker does not resolve __abs64(). I thought _abs64() was suppose to be in the CRT library. Any hints for a solution? c:\devwl\llvm\lib\CodeGen\SelectionDAG\DAGCombiner.cpp(295) : error C3861: 'llabs': identifier not found, even with argument-dependent

I am trying to replicate the following plot using Lattice: http://addictedtor.free.fr/graphiques/graphcode.php?graph=78 I'm having trouble with the lattice equivalent of the "oma" (outside margin) setting. I've been all through the Lattice documentation and others and also searched the lists. Below is sample code that demonstrates where I'm at (it should paste

Dear list, Following a recent enquiry, I've been playing with the idea of creating a colour gradient for a polygon, using the Grid package. The idea is to draw a number of stripes of different colours, using the grid.clip function. Below is my current attempt at this, library(grid) rotate.polygon <- function(g, angle=0){ # utility function, works fine matR <- matrix(c(cos(angle),

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",

There was too many spelling mistakes in my original post so I have decided to re-submit it. So here is it Dear R users, I am trying to determine how many characters can be displayed within the width of an open grid viewport. Unfortunately, the arithmetic operation that seems obvious in this case is not permitted with unit objects (see example below). Although there is a brute force way to get

Hi, I recently created a function which uses grid with a viewport constructed with grid.layout() to position four plots on a plot device. My question is what's the best way to programatically traverse each element of the viewport? The grid is 5x5 and the four plots occupy positions (2,2), (4,2), (2,4), and (4,4). Here's the viewport code: pushViewport( viewport(

Dear R experts, I am plotting the population of students who live in a city, and in successive circular bands made of the contiguous districts that surround the city. This is a stylized figure, where I specify the area of each successive circle based on the cumulative population of students. I want to compare two sets of concentric circles across different populations - such as 'All

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)) ##

Dear list, The dichromat package defines a dichromat function which "Collapses red-green color distinctions to approximate the effect of the two common forms of red-green colour blindness, protanopia and deuteranopia." library(dichromat) library(grid) colorStrip <- function (colors = 1:3, draw = TRUE) { x <- seq(0, 1 - 1/length(colors), length = length(colors)) y <-

The following seems to me to be at least a perverse trap, if not an = outright bug: > is.numeric(unit(1,"npc")) [1] TRUE > is.numeric(1*unit(1,"npc")) [1] FALSE > is.numeric(unit(0,"npc") +unit(1,"npc")) [1] FALSE ...etc. i.e. is.numeric() appears to be TRUE for class "unit" but false for = class ("unit.arithmetic"

Hi All, I have been able to modify the x-axis to start at zero by adding xlow and xhigh parameters; that was pretty simple. I have been unable to find the location of the code that would turn off the information weighting of the box size (I have smaller randomized trials getting less weight than a much larger non-randomized trial). The function is forestplot() from rmeta. Thanks for any

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using JGR R 2.8 with lattice 0.17-15 Note: It's important to you use JGR to use the Java Graphics Device. *** To

I have Samba v 2.28 on RedHat 8.0. (Please don't ask or tell me to update Samba or the OS, as it's not an option right now). This server acts as the PDC for a domain we are setting up. I have this problem that whenever a W2K client (actually I haven't tried it with any other OS) tries to log into this domain (I have, by the way, added the client computer to the Samba server), they get

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 Deepayan and everyone, I need to add a common legend to a group of latice graphs, I have tried different ways using viewport and grid.draw without success. Here is what I have: plot.new() library(grid) library('IDPmisc') print(plot1, split=c(1,1,2,4), more=TRUE) print(plot4, split=c(2,1,2,4), more=TRUE) print(plot2, split=c(1,2,2,4), more=TRUE) print(plot5, split=c(2,2,2,4),

Dear list, I'm trying to produce a plot via xyplot with minimal sourounding white space. However, I cannot find the options in xyplot, ps.options or wherever which prevents lattice from drawing quite some white space around my plot. However, this is quite a problem for me as I want to produce an inset plot inside another lattice-plot. I'm using the panel function to open a viewport and

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus.

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",

How can I divide a unit by an number or average a vector of units, e.g.: u1 <- unit( 3, 'npc' ) u2 <- unit( 6, 'npc' ) u1 / 2 ( u1 + u2 ) / 2 mean( unit.c(u1,u2) ) I would use that e.g. to to calculate the coordinates of the midpoint of a line. Wolfram

Dear Rxperts, Is there a simpler way to generate multipanel grouped individual profile plots? All individuals of a group within a panel have the same color. As of now I am using lattice::xyplot to get the desired effect. Please feel free to suggest other ideas. Also, I am trying to create a generalized function which goes on similar lines like this.. grpPlot <- function(dat, mpgrp=quote(G),
