dumpClass, hasSlot in R?
Venables and Ripley (2000) R Programming (Springer, sec. 5.1) and
Chambers (1998) Programming with Data (Springer) describe functions such
as dumpClass and hasSlot that I can not find in R 1.9.1 for Windows nor
in the "R site search". What do people use for similar functionality?
Also, what resources have people found useful for learning about S4
classes, other than these 2 references?
Thanks, Spencer Graves

Deldir() Thiessen Polygons Problem
Good evening to all.
I find myself trying to create some Thiessen Polygons, in order to finish a
meteorology research.
This is the script I found to create the Polygons:
*
*
*voronoipolygons <- function(x) {*
* require(deldir)*
* if (.hasSlot(x, 'coords')) {*
* crds <- x@coords *
* } else crds <- x*
* z <- deldir(crds[,1], crds[,2])*
* w <- tile.list(z)*
* polys <- vector(mode='list', length=length(w))*
* require(sp)*
* for (i in seq(along=polys)) {*
* pcrds <- cbind(w[[i]]$x, w[[i]]$y)*...

o The pdf() device only includes the definition of the sRGB
