Re: [R] Unadulterated plot
To All, I'm using R 2.8.1. I have attached two images, one shows what I get and the other shows what I want. All I want is the plotting region. Surely there must be a way of plotting individual regions/components in R? Patrizio, I prefer filled.contour() for my data. I still have the same problem (a legend to the right) if I use image() then contour()! Regards, James ps. No need for apologies Simon :D I'm grateful for any assistance fruitless or not.

Re: [R] Unadulterated plot
good point! Provide your own set of x,y,z co-ords, mine are pretty big but you can use any. library(akima) fr3d = data.frame(x,y,z) xtrp <- interp(fr3d$x,fr3d$y,fr3d$z,linear=FALSE,extrap=TRUE,duplicate= "strip") op <- par(ann=FALSE, mai=c(0,0,0,0)) filled.contour(xtrp$x, xtrp$y, xtrp$z, asp = 0.88402366864, col = rev(rainbow(28,start=0, end=8/12)), n = 40) par(op) I tried all these settings too (none of them made a difference)... usr=c(0,845,0,747), mfcol=c(1,1), mfrow=c(1,1), oma=c(0,0,0,0),omi=c(0,0,0,0), plt=c(1,1,1,1) Regards James Peter Alspach wrote: > Kia ora James > > I think it would be easier to provide you with help if you "provide > commented, minimal, self-contained, reproducible code" [see bottom of > this, or any, email to R-help]. > > Hei kona ra ... > > Peter Alspach > > >> -Original Message- >> From: r-help-boun...@r-project.org >> [mailto:r-help-boun...@r-project.org] On Behalf Of James Nicolson >> Sent: Thursday, 19 February 2009 11:22 a.m. >> To: r-help@r-project.org >> Subject: Re: [R] Unadulterated plot >> >> Hi, >> >> Thanks for your help.

Re: [R] Unadulterated plot
Hi, Thanks for your help. I have looked at the beginners documentation and while there are options to configure various aspects of the plot none of them seem to have the desired effect. I have managed to ensure that the plot fills the space vertically with no margins, no axes etc (using mai=c(0,0,0,0)). However, horizontally there remains a margin to the right that pads the space between the filled.contour and its legend. I've tried options to par and filled.contour but I can't seem to remove the legend.

[R] Unadulterated plot
To all, Apologies if this question has already been asked but I can't find anything. I can't seem to think of more specific search terms. I want to display/create a file of a pure plot with a specific height and width. I want to utilise every single pixel inside the axes. I do not want to display any margins, legends, axes, titles or spaces around the edges. Is this possible? Additionally, the plot I am working with is a filled.contour plot and I can not remove the legend? How can I do this?
