Description

Arguments

data	data to use for constructing an environment. For the default with method this may be an environment, a list, a data frame, or an integer as in sys.call. For within, it can be a list or a data frame.
expr	expression to evaluate; particularly for within() often a “compound” expression, i.e., of the form { a <- somefun() b <- otherfun() ..... rm(unused1, temp) }
...	arguments to be passed to (future) methods.

Value

the value of the evaluated expr.
