Dotplots
A high level function and panel function for producing a variant of a histogram called a dotplot.
dotPlot(x, breaks, ..., panel = panel.dotPlot)
panel.dotPlot(
x,
breaks,
equal.widths = TRUE,
groups = NULL,
nint = if (is.factor(x)) nlevels(x) else round(1.3 * log2(length(x)) + 4),
pch,
col,
lty = trellis.par.get("dot.line")$lty,
lwd = trellis.par.get("dot.line")$lwd,
col.line = trellis.par.get("dot.line")$col,
alpha = trellis.par.get("dot.symbol")$alpha,
cex = 1,
type = "count",
