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
