latticeParseFormula: Parse Trellis formula

Description

this function is used by high level Lattice functions like xyplot to parse the formula argument and evaluate various components of the data.

Usage

latticeParseFormula(model, data, dimension = 2,
                    subset = TRUE, groups = NULL,
                    multiple, outer,
                    subscripts,
                    drop)

Value

returns a list with several components, including left, right, left.name, right.name, condition for 2-D, and left, right.x, right.y, left.name, right.x.name, right.y.name, condition for 3-D. Other possible components are groups, subscr
