An extended box and whiskers plot

An extended version of lattice::bwplot(). The only modification is to group and stack box plots if groups is provided.

bwplot2(x, data = NULL, ...)

# S3 method for formula
bwplot2(x, data = NULL, allow.multiple = is.null(groups)
  || outer, outer = FALSE, auto.key = FALSE, groups = NULL,
  drop.unused.levels = lattice.getOption("drop.unused.levels"), ...,
  subset = TRUE)

# S3 method for numeric
bwplot2(x, data = NULL, xlab = deparse(substitute(x)),
  ...)

Arguments

x	see lattice::bwplot()
data	see lattice::bwplot()
...	arguments passed down to lattice::bwplot()
allow.multiple	see lattice::bwplot()
outer	see lattice::bwplot()
auto.key	see lattice::bwplot()
groups	see lattice::bwplot()
drop.unused.levels	see lattice::bwplot()
subset	see lattice::bwplot()
xlab	see lattice::bwplot()

Value

An object of class "trellis". The update method can be used to update components of the object and the print method (usually called by default) will plot it on an appropriate plotting device.

Examples

bwplot2(variety ~ yield,
        groups = site,
        data = barley,
        par.settings = tactile.theme())
