Dear list, I have to plot some geometrical shape given as list of points. My need is the following: let's say my shape is a 1 inch large square; how can I plot it with R in a graphic format that gives me an image *exactly* 1 inch large? I tried to set oma, mar and fin parameters, but with no success. I'm currently using the xfig driver for the final images are to be included in latex

Hi r-users, I would like to overlap 2 ecdf plots.  I tried this below and it gives me two plots of ecdf but just both just in black. par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i") plot(ecdf(datobs)) lines(ecdf(gam_sum_gen)) Then I try to add colors etc and also the legend but fail. par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i")

Dear all r-users,   I have this code below to draw two squares, small and big square.  I would like to colour the small square with red and the big square with blue for example.  I tried using polygon but fail.  Thank you so much for your help.     par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i") plot.new() plot.window(xlim= c(0,8),

Hello, Is it possible to remove those extra margins on the "sample" axis from plot.dendrogram: par(oma=c(0,0,0,0),mar=c(0,0,0,0)) ddr<-as.dendrogram(hclust(dist(matrix(sample(1:1000,200),nrow=100)))) stats:::plot.dendrogram(ddr,horiz=F,axes=F,yaxs="i",leaflab="none") vs. stats:::plot.dendrogram(ddr,horiz=T,axes=F,yaxs="i",leaflab="none")

I am trying to produce a postscript plot consisting of rectangles and text labels in R. It is going very well, but I have been unable to get small margins on the page. I read the documentation on the 'mar' and 'oma' options, but they claim that the margins should default to being 0.25in wide, in fact on my plot they are more like 1in each! Here is the smallest R script that

Hi, how can I convert the unit "lines" of par("mar") into inches? par("mai") could help, but does not (see code below). I want to plot a curve in a predefined size in pdf (I add some margin space to the plot width&height, everything is in cm): pdf("test.pdf",width=(20+2+4)/2.54,height=(10+3+1)/2.54) plot(10:30,

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

Hi all, I'm trying to figure out a way to create a data graphic that I haven't ever seen an example of before, but hopefully there's an R package out there for it. The idea is to essentially create a heatmap, but to allow each column and/or row to be a different width, rather than having uniform column and row height. This is sort of like a Marimekko chart in appearance, except that

The code I'm using is shown below. I would like to have a larger median at the top of the plot so that I can show the entirity of "title_text". Several times I tried messing with "par(mar", but that seemed to make matters worse. By any chance can anyone provide any insight as to the best way to increase the top/upper/northern margin, so the entirity of the title is

I propose the following small changes to pairs.default. The point is to allow control of the outer margin settings, so that there is for example room for legends. [Note also the issue re the setting of par()$usr on exit] ---------------------------------------------------------------- (1) Replace function (x, labels, panel = points, main = NULL, font.main = par("font.main"),

Dear List, yes, me again trying to work with qplot ;-) I would like to make several single plots within a loop, like this (simplified and so on...): trials <- c("A","B","C") mycolours <- ("wheat","darkolivegreen","lightgreen",

Hi, I'd like to produce a marginless or zero margin plot so that the pixel coordinates represent the mathematics. xy<-data.frame(x=c(0,1,1,0,0),y=c(0,1,0,0,1)) png('junk.png',width=300,height=300) par(mar=c(0,0,0,0)) plot(xy$x,xy$y,xlim=c(0,1),ylim=c(,1)) dev.off() The resultant file has about a 10 pixel margin around these lines, and I'm not sure what parameter or function

Hello all, I found a funny problem with y-axis labels when plotting acf(matrix) - the labels are too close to one of the margins and cut in half. Here's the problem: test<-matrix(rnorm(200),ncol=4) acf(test) This doesn't fix the problem: test<-matrix(rnorm(200),ncol=4) par(mar=c(3,3,2,0.2),oma=c(0,0,0,0)) acf(test) This does fix the margin. I understand why, but not sure why ONLY

Hi, I produce a series of diagrams with R in order to include them in my documents (LaTeX). However, there is a white border around the diagrams. For some that do not have anything written at the very bottom, the white border is relatively large. The rather big space between figure and caption at the final document looks not nice. It would be best not to have any white border. I played with

Misunderstanding with lines(...) : http://7d4.com/r/ I would like the y coordinate of the horizontal line to be 1/4, and also the line to begin at x=0 and end at y=1. I'm obviously missing something ... so if anybody could help. Many thanks. test = function() { bmp('test.bmp', width=100, height=100) m = matrix(0, 2, 2) par(new=T, fig = c(0,1,0,1), mai=c(0,0,0,0), mar=c(0,0,0,0),

Hi! Does anyone know hot to save (to png, pdf, ...) only plot area. That is without box around, titles, axis, ... I tried: par(mar=c(0,0,0,0)) and it works for internal viewer (linux and windows). But when I save the image in png it adds that annoying margin around plot area. Any ideas? by, Tine

code: op <- par(bg='black',fg='gray',col='gray',col.axis='gray',col.lab='gray',col.main='gray',col.sub='gray',mai=c(0,0,0,0), tck = 0.01, mgp = c(0, -1.4, 0), mar=c(0,0,0,0)) plot(x,y,ylim=c(-20,20),xlim=c(min(x),max(x)),pch='X',col = rgb(1,1,1, 0.5),yaxt="n", ann=FALSE) abline(v=c(min(x),max(x)), lty=3,

Hello All, I am trying to make a figure with 3x2 plots in it. Let us name the plots as such: 1 2 3 4 5 6 I begin my script with: par(mfcol=c(3,2)) par(oma=c(0,0,0,0)) --> This is for a postscript figure so I really don't need the outer margins. d=5 par(mar=c(d,d,d,d)) --> This applies to all the 6 plots. Now if d=0, plots 1-2,3-4 and 5-6 will have no gap between them and

I am trying to plot a figure within a figure (an inset that shows a closeup of part of the data set). I have searched R-help and other sources but not found a solution. What I would like to do is (1) produce a plot (2) specify a window that will be used for the next plot (in inches or using the coordinate system of the plot produced in (1) (3) overlay a new plot in the window specified under (2)
