It has been my experience that the R-graphics experts generally  
deprecate 3-D bar graphs, but there are some worked examples in the  
supporting webpages for Sarkar's "Lattice" book:

cloud(density ~ long + lat, state.info,
           subset = !(name %in% c("Alaska", "Hawaii")), type = "h",  
lwd = 2, zlim = c(0,
                             max(state.info$density)), scales =  
list(arrows = FALSE))
library("maps") state.map <- map("state", plot=FALSE, fill = FALSE)
panel.3dmap <- function(..., rot.mat, distance, xlim, ylim, zlim,  
xlim.scaled,
     ylim.scaled, zlim.scaled) {
            scaled.val <- function(x, original, scaled) { scaled[1] +
                         (x - original[1]) * diff(scaled) /  
diff(original) }

  m <- ltransform3dto3d(rbind(scaled.val(state.map$x, xlim,  
xlim.scaled),
              scaled.val(state.map$y, ylim, ylim.scaled),  
zlim.scaled[1]),
              rot.mat, distance) panel.lines(m[1,], m[2,], col =  
"grey76") }
