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)

James

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.

Kind Regards,
James

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?

Simon.

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?

Kind Regards,
James

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(<akima data>, *) on finer grid")
contour(akima.smooth, add = TRUE,drawlabels=F)

cheers

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.
