Also, the result of hexbin() will be an S4 object instead of a list. There is some unfinished discussion going on, if the old version of hexbin should be kept available in package "hexbin0" -- for those of you who can't update quickly to the new API to hexbin graphics.

Hi Jenny, Just to add to what Martin said; We are working on making hexbin much more flexible. The price for the flexibility is using grid, which isn't bad one you get used to it. Under the new model you can simply do something like > x<-rnorm(10000) > y<-rnorm(10000) > hbin<-hexbin(x,y) > hp<-hexViewport(hbin,offset=unit(1.2,"inches"),mar=NULL,newpage=TRUE) > pushViewport(hp) > grid.rect() > grid.xaxis() > grid.yaxis() > hexagons(hbin,style="centroid") > hloess<-loess(y~x,data=hcell2xy(hbin),hbin@count) > grid.lines(seq(-4,4,by=.2),predict(hloess,seq(-4,4,by=.2)),gp=gpar(c ol='red'),default.units="native") > popViewport() etc .... This example would have been a royal pain in the old version, because of having to manipulate pars and still may not have worked. This should allow very flexible construction of plots, for instance all the different plot types in hexbin are now created using hexViewport. Hope this will be useful Nicholas On Thu, 21 Oct 2004 22:28:43 +0200, "Martin Maechler" <maechler@stat.math.ethz.ch> said: > >>>>> "Jenny" == Jenny Bryan <jenny@stat.ubc.ca> > >>>>> on Thu, 21 Oct 2004 10:17:19 -0700 writes: > > Jenny> Are there any plans for changing the behavior of > Jenny> "plot.hexbin" w.r.t. the graphics parameters, > Jenny> especially 'par("usr")'?
