Hi: One way is to create a vector of pch values that you can pass into xyplot, e.g.,
dd <- data.frame(x = 1:10, y = 1:10, pch = c(rep(1, 5), 16, rep(1, 4))) library('lattice') xyplot(y ~ x, data = dd, pch = dd$pch, col = 1) HTH, Dennis On Fri, Sep 30, 2011 at 12:01 AM, Kang Min <ngokang...@gmail.com> wrote: > Hi all, > > I was wondering if there's an equivalent to par(new=T) of the plot > function in lattice.
