Default Panel Function for stripplot

This is the default panel function for stripplot. Also see panel.superpose

Usage

panel.stripplot(x, y, jitter.data = FALSE,
                factor = 0.5, amount = NULL,
                horizontal = TRUE, groups = NULL,
                ...,
                grid = lattice.getOption("default.args")$grid,
                identifier = "stripplot")

Arguments

x,y

coordinates of points to be plotted

jitter.data

whether points should be jittered to avoid overplotting. The actual jittering is performed inside panel.xyplot, using its jitter.x or jitter.y argument (depending on the value of horizontal).

factor, amount

amount of jittering, see jitter

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.

groups

optional grouping variable

...

additional arguments, passed on to panel.xyplot

grid

A logical flag, character string, or list specifying whether and how a background grid should be drawn. In its general form, grid can be a list of arguments to be supplied to panel.grid, which is called with those arguments. Three shortcuts are available:

TRUE:

roughly equivalent to list(h = -1, v = -1)

"h":

roughly equivalent to list(h = -1, v = 0)

"v":

roughly equivalent to list(h = 0, v = -1)

No grid is drawn if grid = FALSE.

identifier

A character string that is prepended to the names of grobs that are created by this panel function.

Details

Creates stripplot (one dimensional scatterplot) of x for each level of y (or vice versa, depending on the value of horizontal)
