similar to: the C function drawing a rectangle: heatmap() -> image() -> do_image() -> GRect() -> GERect() -> rect() -> do_rect() -> GRect() ??

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Hi, We sometimes see offers to contribute, asking what needs to be done. If they know C, how about the 111 FIXMEs? But which ones would be most useful to fix? Which are difficult and which are easy? Does R-core have a process to list and prioritise the FIXMEs? ~/R/Rtrunk/src/main$ grep "[^/]FIXME" * | wc -l 111 ~/R/Rtrunk/src/main$ grep -A 1 "[^/]FIXME" * arithmetic.c:/*

Dear all, I haven't been working with R before, but has been asked by my colleagues to investigate the possibility of using R plotting capabilities from external (C) code. They have several plotting functions, implemented in R, that are needed to be included in a front-end Windows-based application. As far as I understood, R.dll is a dll that serves external R calls. 1) My first question is

May I raise the issue of the behaviour of image()? In image() dim(z) is supposed to be c(length(x), length(y)). This suggests that the user is supplying the midpoints of the rectangles. For all but the outer rectangles this is true. The outer rectangles, however, are only displayed in half width. So it is not possible to show correctly an image plot of equally-spaced abscissa. I would hazard

These files implement the wxRect class. I couldn''t think of any particular reason not to implement this. Roy _______________________________________________ wxruby-users mailing list wxruby-users@rubyforge.org http://rubyforge.org/mailman/listinfo/wxruby-users

I would like to add vertical shaded blocks in plot.xts graphs (like recession periods in FRED graphs) The reason I use plot.xts instead of plot.zoo is that I like the fact that the grid is automatically aligned with major ticks in plot.xts. xblocks() and rect() do not seem to work with plot.xts (only with plot.zoo). Are there any alternative methods that work with plot.xts? Thanks. -- View

Full_Name: Joe Voelkel Version: 2.4.0 OS: Windows XP Submission from: (NULL) (129.21.11.37) Using "border=NA" in the call to rect generates an error. But the help file says border=NA is acceptable. (The problem is that border=NA evaluates to TRUE for "is.logical(border)" inside the function. Using rect with border=FALSE works fine)

Dear all, I have a question about how to load data or (entering data )to each cell of a rectangle created by rect . e.g. I have a matrix rbind(1:2,1:2) I have created a 2x2 rectangle by using: a<-0:1/10 b<-0:1/10 kk<-expand.grid(a,b) plot.new() rect(kk[, 1], kk[, 2], kk[, 1] + .1,kk[, 2] + .1) so how do we put the value of rbind(1:2,1:2) into the relevant

Hello everyone, I am trying to understand how plot axis and rect might work together I would like to plot some values on a plot with x(0,100) and y(0,100) i want to see all the values from 0,1,2,3,4,5,.....100 written in the x and y axis. At the same time I want some grid to easily see when y and x values cross. Finally I want to paint red two of the cells created by this grid. I am trying

Hi, I have the following code: hist(gps$heartpercent, breaks=5) rect(90, par("usr")[3], 100, par("usr")[4], col = "red") How do I get the rectangle to appear behind the histogram. Barring that, how can I make certain bars of the histogram to be a certain color? Thanks, Jason

I've found that while cutree() and rect.hclust() make the same classes for a given height in the dendrogram, the actual labeling of the classes is different. For example, both produce the same 4 classes but class 1 according to cutree() is class 4 according to rect.hclust(). Would it be possible that future versions provide the same labeling? rect.hclust() is useful to display the classes

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,

I have tried to use rect.hclust() to draw a rectangle around a set of leaves, but am running into trouble. The rect.hclust() is drawing two rects instead of one, and of the wrong size: -------------------- scoreClusterObj <- hclust(scoreDistanceObj, method=clustMethod) order <- scoreClusterObj$order orderedLabels <- rep(0, length(order)) for (orderIndex in 1:length(order)) { # this

Hello. I have another rect question. If I want to make a lot of rectangular, without borders, and without any spaces between them, how could I do it? I.e. > plot(-1:1., -1:1., type = "n") > rect(0,-1,1,1,col="red",lwd=0,border=F,xpd=T) > rect(-1,-1,0,1,col="blue",lwd=0,border=F,xpd=T) will produce two rectangular, but there is space between them. How

Dear r-help, Sleep-deprivation from having 2 youngsters under 2 around the house is fuzzing my brain, so please be gentle if the answer to this query is obvious! In the example below, I'm trying to use grid.rect to add grey rectangles to the panels of a lattice plot to indicate which months spawning occurred of a (very cute) native Tasmanian fish. The fish in the two lakes spawned at

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,
