similar to: rect function

Dear all, I am stuck at applying loop function for creating separated plots. I have coding like below: dataset.table <- table(data.frame(var1=c(1,2,3,1,2,3,1),colour=c("a","b","c","c","a","b","b") )) kk = function(f) { ls=as.character(f) pie(dataset.table[ls,],main=ls)

Hello anyone used to do similar things: search for the final C function that corresponding to the drawing of a rectangle? As listed in the subject, I started from heatmap() in R and after several steps reached the GRect() in C. However, then it refers to rect() which further seems to refer to do_rect(), and then, surpringly, do_rect refers to GRect()!!! A dependency circle! How can it work if no

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

Hi all, I've found quite usefull colored-grid created by image() but I'm facing a doubt I am not able to solve. Given the following data rectangle... 1 2 3 4 5 6 7 8 9 10 11 12 13 14 1 12 22 0 7 2 1 0 2 0 2 6 -3 0 3 2 0 -1 0 9 3 -4 0 0 0 0 3 0 0 0 3 29 45 6 12 16 85 -2 0 -3 -4 89 -1 -1 1 4 2 9 3 6 17 3 -2 -9 -2 8

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

Hi everybody, I just notice a strange behaviour of gpar's fill argument when using non-postscript devices: The default of the argument is transparent (according to get.gpar("fill")). So as expected, the following code draws a nice red rectangle in the middle of my X11 or postscript device. pushViewport(viewport(width=0.5, height=0.5)) grid.rect(gp=gpar(fill="red"))

Hello everyone, if I have: x=1:10 y=1:10 plot(x,y) and I plot a rectangle rect(4,0,6,11, col=5) it covers the points of the graph. Is there a way to draw the rectangle under the points? I was thinking the a solution could be draw an empty plot then draw the rectangle and after the points, but it did not work. Any idea? thanks for your help H. [[alternative HTML version deleted]]

I am trying to create a lattice plot and would like to later, i.e. after the plot is drawn, add a grey rectangle behind a portion of it. The following works except that the rectrangle is on top of and obscures a portion of the chart. I also tried adding col = "transparent" to the gpar list but that did not help -- I am on windows and perhaps the windows device does not support

Hi, when using the grid package, I've come across this weird behaviour where a call to plot.new() will start a new page for a multi-page pdf, but then the margins will somehow behave strangely for all but the first page: here is some code: pdf("test.pdf"); plot.new(); grid.rect(gp = gpar(fill="blue")); plot.new(); grid.rect(gp = gpar(fill="blue")); dev.off()

Hi, I am trying to add a rectangular colored background area to a plot of a time series of relative price changes. I believe that what I'm trying to do is very similar to the question and example given here: http://www.mail-archive.com/r-help at stat.math.ethz.ch/msg73948.html http://www.mayin.org/ajayshah/KB/R/html/g5.html My problem/difference is that my time series looks like so: >

Hi I want to draw a rectangle behind a barplot such that it highlights those particular bars from the rest of the plot. I have figured out how to draw a barplot(), and then how to draw a rectangle of the correct shape and size (using rect()), but when I use rect() it draws over the top of the bars, and then when I re-draw the bars, it draws with a white background, thus eliminating my rectangle!

How do I draw a rectangle across multiple plots on a device? E.g., def.par <- par(no.readonly = TRUE) par(mfrow = c(3, 1)) plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") rect(2, -4, 3, 4) par(def.par) I want the rectangle to extend across the whole device. 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

Hi, Is it possible to diagonally fill a rectangle with a color gradient? I noticed that the gradient.rect of plotrix could fill a rect either up and down or from side to side. I am looking for something similar but fills diagonally instead, e.g., from the upper left corner to the bottom right. Does anyone know how to do it in R? Thanks, -- Tom [[alternative HTML version deleted]]

Hi, I need some suggestion on how I could modify the color on some rectangle that I have created using "image". In other words, I have a 5x5 matrix, say, m. m <- matrix(rnorm(25), nrow=5) I create a grid of rectangles by: image(m) Now I want to change the color of rectangle (3,3) to blue. I don't know how this could be done, and searching the web has

All, I have a simple plot(x,y) and I would like to then insert rectangles of some length (in native coordinates) and height fixed to 0.5 in native coordinates. I can't quite get the code right to do this. Can anyone give me a quick example of how to do this? I looked the gridBase index and the tutorial (from R-news?) but just haven't gotten it down yet. > plot(1:10,1:10)

Hi there, I found one reference to add a reactangle behind a plot using plot(...,add=T), I tried this but didn't obtain the desired result. If a I have the following code: plot(x,y) rect(xleft, ybottom, xright,ytop,col='green) The rectangle appear on top of the plot. Any help will be greatly appreciated, Judith

Hi all, I would like to ask your help to add a color band (Ι am not sure regarding the right term, this color band at the right of the plot "describing" values with their corresponding color. For now I have only this code test<-matrix(data=runif(10000),nrow=100) plot(test,axes="FALSE") axis(1,at=c(0,1),labels=c("a","b")) # but  I would like to add
