y
A character string indicating which column of x contains the capture patterns.
cont.vars
A character vector of variable names for continuous variables.
categ.vars

Value

A data frame that is an expanded version of the argument x. Variables are renamed using an "x.con...." or "x.dis...." for continuous and discrete variables, respectively.
