[R] Changing size of lattice plot?
Hi I am having a bit of difficulty with changing the canvas size on a trellis/lattice plot. I am plotting two cubes of 3-dimensional random numbers, as follows: library(gsl) library(lattice) q - qrng_alloc(type=sobol, 3) npoints - 200 rs - qrng_get(q,npoints) # Plot the normal variates in a 3-dim cube p1 - cloud(rnorm(npoints) ~ rnorm(npoints) + rnorm(npoints), xlab=x, ylab=y, zlab=z, pch=21, main=paste(npoints,3-Dimensional ~N(0,1))) p2 - cloud(rs[,1] ~ rs[,2] + rs[,3], xlab=x, ylab=y, zlab=z, pch=21, main=paste(npoints,3-Dimensional Sobol)) print(p1, split=c(1,1,2,1), more=TRUE) print(p2, split=c(2,1,2,1)) This plots fine, however the canvas size is much too large - there is a large amount of whitespace above and below the cloud plots. I have tried fiddling with the margins, e.g. trellis.par.set(layout.heights = list(top.padding = -20, main.key.padding = 1, key.axis.padding = 0, axis.xlab.padding = 0, xlab.key.padding = 0, key.sub.padding = 0, bottom.padding = -20)) But this just moves the figure and legend around inside a fixed-size canvas. Does anybody know how I can set the base height and width of a lattice plot?

Re: [R] Changing size of lattice plot?
The 'base height and width of a lattice plot' are the dimensions of the graphics device in use. You set those when you open the graphics device (which you are using was unstated, as was your OS), and each device has device-specific defaults. I'd suggest something like windows(width=8, height=5) x11(width=8, height=5) ... would be more appropriate, but for a screen device you can resize the window to get the effect you are looking for.

I am using this plot within Sweave, so the code in my orginal email is within a = block. If I place a call to windows() just before I print() the lattice plot, then I get an access denied error when generating the TeX file, as R has not closed the PDF file. If I place a call to dev.off() just before the end of the block, it doesnt seem to make any difference...I presume this is because of the interaction with Sweave opening and closing its own device within the scope of the block. Is there any solution for this, or do I need to manually call pdf() and \includegraphics here? You can tell Sweave about width and height for each chunk: see its manual for details. -- Brian D.
