dear list, i have a problem using the par function. in one graphic device i want to have two plots so i tried to use par(mfror=c(1,2)). of course it worked out, but the height now is twice the length of the width for each single plot. what i actually wanted is something like par(mfrow=c(2,2)) where only the top (or bottom) two plots are drawn with entire length proportions of 1 to 2 ( height 1,

Hi all, Please, while using image() which is the graphical parameter which control the space between ylab and the y axis? I do need to write a number of relatively long y labels and I am not able the control, if possible, this space. See the effect I need to avoid... http://nvx.environmentalchange.net/@rrodriguez/images/overlapping.jpg Thanks for your help, Ricardo -- Ricardo Rodr?guez Your

hi everybody, I noticed the following: in one of my scripts 'layout' is used to generate a (approx. square) grid of variable dimensions (depending on no. of input files). if the no. of subplots (grid cells) becomes moderately large (say > 9) I use a construct like ###layout grid computation and set up occurs here### ... opar <- par(no.readonly = T);

Hello, I would like to plot specific SNPs with their exact locations on a chromosome. Based on my genotyping results I would like to separate these SNPs in three different categories: 1, 2 and 3 and use different colours to represent these categories. The script below generates the sample data. I can plot these with the image function using the following: val <- 1:3 samp <- sample(val,

Hello, I'm willing to plot a sequence of densities on a 3d graph, something like ----------------------------------------------------------------- x <- sapply(1:10, function(i)rnorm(1000)) f <- sapply(1:10, function(i)density(x[,i], from=-5,to=5)$y) grid <- density(x[,1], from=-5,to=5)$x win.graph() persp(grid1, 1:10, f,theta=-50, phi=30, d=2)

Dear all, I have the following problem: I have written a function genereating to plots, eg myfunction <- (data, some.parameters) { #some calculations etc . par (mfrow=c(1,2)) plot1(......) plot2(.....) } which works fine. But for analysing several variants, I tried a slope, eg: par (mfrow=c(5,5)) for ( i in 1:10) { myfunction(data, i) } Off

Applying the following patches closes the following task (part 1 was already taken care of). TASK: New Problems STATUS: Open FROM: <Kurt.Hornik@ci.tuwien.ac.at> New minor remarks: * The documentation for `image' still has the old order z, x, y. * Perhaps one should add `par(ask = T)' in the image demo? * Perhaps one should save the original value

Greetings, I would like to use a data.frame with strings to feed the expression() in the title of a plot. The way I did this is: molecules <-data.frame(name=c("o3","no","no2"),expression=c("quote(O[3])","quote(NO)","quote(NO[2])")) for (mol in c(5,7,9)) { plot(x, y, type="b",

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 R-devel, Kurt had alerted me to the problem that the randomForest package that I maintain has been failing checks in R-devel. However, I just can't see why or where it's failing. I'd very much appreciate any pointer. The failure occur when running the example code in varImpPlot.Rd: > varImpPlot(mtcars.rf) Error in par(opar) : invalid value specified for graphical parameter

I've just started learning R, so I'm still on the steep part of the learning curve, but my enthusiasm was heightened by learning that there's a very nice implementation of mosaicplot(). As a learning project, I've already done a basic implementation of a pairs.table() function which does a mosaic scatterplot matrix, and now I'm trying to do conditional mosaic plots (discrete

Dear List, Suppose I want to do a demonstration with R, which I will be showing a couple of different graphs (e.g. demo(graphics) ). However I want R to run through each graphics automatically. I can achieve this by changing the line in demo(graphics): opar <- par(ask = interactive() && (.Device %in% c("X11", "GTK", "windows",

R 2.4.0 for Windows The following plot appears as a squared window (as all r-plots) Not all subtitles are visible, but all subtitle will appear, when changing the aspect ratio of the plot window with the mouse to a wide format. But does not work when using the save as postscript menu item from the plot window. is there any solution for that? opar <- par(mfrow = c(2,2), oma = c(0, 0, 1.1,

Dear All, Would you please tell me how to display the sample No. on the map ? ---Below commands don't display the sample No.(from 1 to 150).--- library(som) library(klaR) iris.som3 <- som(iris[,1:4], xdim = 14,ydim = 6) library(klaR); opar<- par(xpd = NA) shardsplot(iris.som3, data.or = iris,label = TRUE) legend(3.5,14.3, col = rainbow(3), xjust =0.5, yjust = 0,legend =

Is there a way to achieve lbl=c("a", "b", "c", "d") par(mfrow=c(2,2), ann=FALSE) for (t in 1:4){ plot(seq(from=1,to=2*pi,length=100), sin(t*seq(from=1,to=2*pi,length=100)), type="l") title(main=paste("(", lbl[t], ")", sep="")) } without having to use an object like 'lbl'? More generally: is it possible

My code is as follows: #include <iostream> #include <cmath> using namespace std; #define MATHLIB_STANDALONE 1 extern "C" { #include "R_ext/Applic.h" } typedef struct TT{ double ** tempX; double * tempY; int tempN; } TT, *MM; double fn(int N, double * beta, void * ex){ double total = 0; int i = 0,j = 0; double * betaFn = new double[N]; MM tmp = (MM)ex;

Dear all, I have a simple plot using "gridBase" like this. The problem occurs whenever I execute this code there is always a blank page created before the actual plot. How can we disable that blank page? I am using: R version 2.7.2 (2008-08-25) and gridBase version: 0.4-3 __ BEGIN__ library(grid) library(gridBase) opar <- par(no.readonly=TRUE) par(opar) grid.newpage()

Clearly, barplot should have an `axes' argument.

I just downloaded rw1041 (the latest windows binary). Everything installed fine. When I start a new Rgui, and type "demo(graphics)", after pressing return to start, a graphics window appears. When I get to the second prompt: > opar <- c(opar, par(bg = "white")) > plot(x, ann = FALSE, type = "n") Hit <Return> to see next plot: at this
