Re: [R] Unadulterated plot
Hi James, What you really need to do is to check out the many freely available pdfs for R beginners. Here is a good place to start http://cran.r-project.org/other-docs.html If I am right interpreting what you want, I think you need to create a blank plot with no axes, axis labels etc. Try plot(x,y,xlab="",ylab="",xaxt=NULL,yaxt=NULL,type="n") #blank plot points(x,y) type "?par" into R and see how you can set parameters like this up as the default. Hope this helps?

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.

Re: [R] Unadulterated plot
James, you're probably interested in image function rather than in filled.contour. Type ?image to see the syntax. Cheers, Patrizio 2009/2/18 James Nicolson : > Hi, > > Thanks for your help.

Re: [R] Unadulterated plot
James, as I previously told you in my broken English, probably the function you're looking for is not filled.contour but image and contour The following code makes exactly what you ask for data(akima) akima akima.smooth <- with(akima, interp(x, y, z, xo=seq(0,25, length=500), yo=seq(0,20, length=500))) op <- par(ann=FALSE, mai=c(0,0,0,0)) image (akima.smooth, main = "interp(, *) on finer grid") contour(akima.smooth, add = TRUE,drawlabels=F) cheers Patrizio 2009/2/19 James Nicolson : > good point!

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.

I still have the same problem (a legend to the right) if I use image() then contour()! I don't see why you'd get a legend in that case. But it's hard to get the contour lines to match the colour changes when using image with contour, so I can see why you might prefer filled.contour. I think you're going to have to edit filled.contour to do what you want. It's not too hard: just comment out the code that sets up the layout, then everything until just before the second plot.new(). Insert par(mar=c(0,0,0,0)), and you'll get a filled contour plot with no margins. Duncan Murdoch Regards, James ps. No need for apologies Simon :D I'm grateful for any assistance fruitless or not.
