Hi everyone I want a square scatterplot with abline(0,1) going exactly through the SW and NE corners. By "square" I mean that the plotting region is exactly square, and that the axis limits are identical. x <- 1:20 y <- x+rep(c(-1,1),10) lims <- range(c(x,y)) None of the following do this: plot(x,y) ; abline(0,1) #not square plot(x,y,asp=1);abline(0,1) #diagonal

Hello there, I have a fairly simple request (I hope!) I have produced a filled contour plot like this: library(grDevices) library(gplots) library(plotrix) filled.contour(contour, axes=F, frame.plot=TRUE, color=terrain.colors, ylab= "Length Along Flume (m)", key.title = title(main="Velocity\n(m/s)"), key.axes = axis(4, seq(0, 0.6, by = 0.1)), asp=2, plot.axes = {

Dear All, I've been playing with pty, and it seems it does not produce square plots as it is expected to (or at least as I expect it to). Consider this simple example: par(pty="s"); plot(1:10, 1:10) This should produce a square plot, right? Well, if you have a look at the graph, it is not square! So, maybe the limits? par(pty="s"); plot(1:10, 1:10, xlim = c(0,11),

#See David Williams' book "Weighing the odds", p286 y <- c(1.21, 0.51, 0.14, 1.62, -0.8, 0.72, -1.71, 0.84, 0.02, -0.12) ybar <- mean(y) ylength <- length(y) ybarv <- rep(ybar, ylength) x <- 1:ylength plot(x,y,asp=1,xlab="position",ylab="ybar",type="n",ylim=c(-1,1)) segments(x[1], ybar, x[ylength], ybar) segments(x,ybarv,x,y)

Hello, I want to plot 21 scatter plots in a 7*3 matrix on a single A4 page (using mfcol). Below is an example, which -by and large- looks very close to the desired result. But I do not get it to fill out the whole page. If I specify the a different page size, the plots still do not fill out the whole page. Anybody an idea what to do? Maybe adjusting indvidiual plot size (if so, how?). Or is there

Hi! I'd like to plot things with axes going from the highest to the lowest value, so that e.g. high values on the xaxis are plotted to the left and low values to the right. Could anyone tell me how this is done? I couldn't find anything in the documentation. Thanks a lot! Silli

I have a function for plotting soil texture that I am having a problem with. The function is: plot.psd <- function(sand, clay, ...) { conv.ter <- function(x, y) { x.con <- 100 - x - y*cos(1/3*pi) y.con <- y*sin(1/3*pi) data.frame(x=x.con, y=y.con) } plot(conv.ter(sand, clay), xlim = c(0,100), ylim = c(0,100*sin(1/3*pi)), axes = FALSE, xlab="",

Greetings, Folks. I'd appreciate being shown the way out of this one! I've been round the documentation in ever-drecreasing circles, and along other paths, without stumbling on the answer. The background to the question can be exemplified by the example (no graphics window open to start with): set.seed(54321) X0 <- rnorm(50) ; Y0 <- rnorm(50)

I am interested to know how to make for clouds: - aspect ratio = 1 - labels attached to points - vertical lines from the points to the x/y base plane I tried: t = c( 'A', 'B', 'C', 'D' ) x = c( 100, 0, 200, 100 ) y = c( 0, 100, 0, 100 ) z = c( 80, 0, 20, 40 ) q = data.frame( x, y, z ) rownames( q ) = t print(cloud( z ~ x *

set.seed(1) x <- rnorm(n = 1000, mean = 0, sd = 1) plot(x = x, asp = 2000) Could someone please explain what the 'asp' parameter is doing?

I have the following codes but can anyone make it shorter i.e making these FOR loop into one loop ... thanks... par(mfrow=c(2,4)) for(i in 16:23){ hist(data[,i],main=paste(colnames(data)[i],sep=""),ylab="Frequency",xlim=c(1,5),xlab="Score",ylim=c(0,100)) } png("histogram.png") dev.off() par(mfrow=c(2,4)) for(i in

Suppose I have the following data I want to scatterplot: > xy [,1] [,2] [1,] 0 0 [2,] 21 4 I start up a graphics window and fire away: > plot(xy) - but because the graphics window is square, the aspect ratio is wrong. So I add: > plot(xy, asp=1) - now the aspect ratio is correct, but the Y range is about -8 to 11, whereas my data has a Y range of 0

Hi all, Does anyone know of a fairly easy way to "stretch" a heatmap vertically? I've got 42 arrays and would like to be able to see as many significant genes as possible (right now I can only get 50 genes with it still being readable). In some comparisons there are several hundred significant genes. I've fiddled with the "asp" argument, but that doesn't

Hi, I am gradually moving from the classical R plot functions to the library Lattice I have some questions about contourplot () and its arguments: 1/ I am working on geographical coordinates which makes necessary that the X (longitude) and Y (latitude) units be represented with the same distance on screen. This was obtained in the classical R plots with plot.default(x,y, asp=1,...) and then

How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

hello, i try to plot 3 graphs which have the same x.axis underneath each other. i'd like the plots to be aligned without margings between the boxes and draw a single x axis beneath the lowest plot. i managed to get the alignment by setting par(mar), but the middle box is stretched and i cant't figure out how to get around this. par(pin) was my guess, but this doesn't do the job

Dear R-users I have a problem choosing initial points for the function arms() in the package HI I intend to implement a Gibbs sampler and one of my conditional distributions is nonstandard and not logconcave. Therefore I'd like to use arms. But there seem to be a strong influence of the initial point y.start. To show the effect I constructed a demonstration example. It is reproducible

I almost always supply my own aspect ratio when plotting using lattice. When I plot these to pdf, I would like to specify pdf dimensions that will result in minimal margins around the plot. In my application, resorting to a pdf cropper after plotting is not an option - I must do it in R. The problem is that I cannot determine the correct aspect ratio for the overall plot (accounting

Hi I've been playing with a 3x2 graphics device using the default size as it appears on screen. This has given me tall thin plots which I can resize by dragging the window and increasing the window width. However I was wondering if I can force R to produce square plots or set the actual aspect ratio. asp seems to affect data units, not on-screen pixel units. thanks mike -- View this
