Re: [R] equal spacing of the polygons in levelplot key (lattice)
OK, how about this instead? # library('lattice') levs - as.vector(quantile(volcano,c(0,0.1,0.5,0.9,0.99,1))) levq - seq(min(levs), max(levs), length = 6) levelplot(volcano, at = levs, colorkey = list(at = levq, labels = list(at = levq, labels = levs) )) Dennis On Wed, Nov 16, 2011 at 10:27 AM, Andy Bunn andy.b...@wwu.edu wrote: -Original Message- From: Dennis Murphy [mailto:djmu...@gmail.com] Sent: Tuesday, November 15, 2011 8:54 PM To: Andy Bunn Cc: r-help@r-project.org Subject: Re: [R] equal spacing of the polygons in levelplot key (lattice) Hi: Does this work?
