Once you guys figure all this out, I'm glad to modify bplot to pass more arguments lattice if needed. Frank E Harrell Jr Professor and ChairmanSchool of Medicine Department of Biostatistics Vanderbilt University On Fri, 13 Aug 2010, David Winsemius wrote:

[R] How to add lines to lattice plot produced by rms::bplot

2010-08-13 Thread David Winsemius
I have a plot produced by function bplot (package = rms) that is really a lattice plot (class=trellis). It is similar to this plot produced by a very minor modification of the first example on the bplot help page: requiere(rms) n - 1000# define sample size set.seed(17) # so can

Hi David I do not know if you have done something like this. I tried str(bp.plot) which gave the section about the regions (for colours) as: $ panel.args.common:List of 8 ..$ x : num [1:2500] 27 28 29 29.9 30.9 ... ..$ y : num [1:2500] 141 141 141 141 141 ... ..$ z : num
