dotPlot: Dotplots

Description

A high level function and panel function for producing a variant of a histogram called a dotplot.

Usage

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",
  ...)

Arguments

breaks,equal.widths,groups,pch,col,lty,lwd,col.line,type,alpha

as in histogram

Examples

dotPlot( ~ age, data = HELPrct)
dotPlot( ~ age, nint=42, data = HELPrct)
dotPlot( ~ height | voice.part, data = singer, nint = 17,
          endpoints = c(59.5, 76.5), layout = c(2,4), aspect = 1,
          xlab = "Height (inches)")
