Arguments

x	A tableby object.
pdata	A named data.frame where the first column is the by-variable names, the (optional) second is the strata value, the next is the x variable names, the next is p-values (or some test stat), and the (optional) next column is the method name.
use.pname	Logical, denoting whether the column name in pdata corresponding to the p-values should be used in the output of the object.
lhs	Logical, denoting whether to remove NAs from the first column of the data.frame (the "left-hand side")
...	Other arguments.
e1, e2	tableby objects, or numbers to compare them to.
n	A single integer. See head or tail for more details

Value

na.tableby returns a subsetted version of object (with attributes). Ops.tableby returns a logical vector. xtfrm.tableby returns the p-values (which are ordered by order to sort).

Details
