panel.needle

Needle Plot Lattice Panel

Description

A variation of panel.dotplot that plots horizontal lines from zero to the data point.

Usage

panel.needle(
  x,
  y,
  horizontal = TRUE,
  pch = if (is.null(groups)) dot.symbol$pch else sup.symbol$pch,
  col = if (is.null(groups)) dot.symbol$col else sup.symbol$col,
  lty = dot.line$lty,
  lwd = dot.line$lwd,
  col.line = dot.line$col,
  levels.fos = NULL,
  groups = NULL,
  ...
)

Arguments

`x, y`	variables to be plotted in the panel. Typically y is the 'factor'
`horizontal`	logical. If FALSE, the plot is ‘transposed’ in the sense that the behaviours of x and y are switched. x is now the ‘factor’. Interpretation of other arguments change accordingly. See documentation of `bwplot` for a fuller explanation.
`pch, col, lty, lwd, col.line`	graphical parameters
`levels.fos`	locations where reference lines will be drawn
`groups`	grouping variable (affects graphical parameters)
`...`	extra parameters, passed to `panel.xyplot` which is responsible for drawing the foreground points (`panel.dotplot` only draws the background reference lines).

Details

Creates (possibly grouped) needleplot of x against y or vice versa
