[R] annotating a filled contours plot with a grid of points

2009-02-06 Thread Dario Martin-Benito
Dear R-help members, I am trying to plot annotate a filled contours plot (with filled.contour) with a grid of points. I have read ways of annotating it with individual points but not with grids in another matrix. Any ideas? Thank you very much. Dario

Dario, Checkout the 'plot.axes' argument to 'filled.contour'. Michael Grant --- On Fri, 2/6/09, Dario Martin-Benito dmar...@inia.es wrote: From: Dario Martin-Benito dmar...@inia.es Subject: [R] annotating a filled contours plot with a grid of points To: r-help@r-project.org Date: Friday,

Try this example: mygrid - expand.grid(x=seq(0,1, by=0.1), y=seq(0,1, by=0.1)) filled.contour(volcano, color = terrain.colors, asp = 1, plot.axes={ axis(1); axis(2); points(mygrid, cex=0.5, pch=19)}) Cheers, Marcelino From: Dario Martin-Benito dmartin at inia.es Subject:
