[R] Controlling line-join style in Lattice

2012-08-22 Thread Morgan, Andrew Parker
R users, I am creating a series of scatterplots with Lattice's xyplot(). Some of the plotting symbols are squares with thick borders. The corners of the squares are rounded by default; I would like them to be square. In base graphics this is easily done with par(ljoin = mitre), and in grid

You can set grid parameters in the grid.pars component of trellis.par.get(). x - 1:4; y - c(1,3,2,4) xyplot(y ~ x, type = l, lwd = 20) # default linejoin ## set linejoin to 'mitre' trellis.par.set(grid.pars = list(linejoin = mitre)) xyplot(y ~ x, type = l, lwd = 20) Peter Ehlers On

I should add that you can also use the par.settings() mechanism to set your linejoin specification on the fly: x - 1:4; y - c(1,3,2,4) xyplot(y ~ x, type = l, lwd = 20, par.settings = list(grid.pars = list(linejoin = mitre))) Peter Ehlers On 2012-08-22 12:28, Peter Ehlers wrote: You can
