Objects from the Class
Objects can be created by calls of the form new("SampleControl", ...)
or SampleControl(...).Details
There are some restrictions on the argument names of the function
supplied to method. If it needs population data as input,
the corresponding argument should be called x and should expect
a data.frame. If the sampling method only needs the population size
as input, the argument should be called N. Note that method is
not expected to have both x and N as arguments, and that the
latter is much faster for stratified sampling or group sampling.
Furthermore, if the function has arguments for sample size and probability
weights, they should be called size and prob, respectively.
Note that a function with prob as its only argument is perfectly valid
(for probability proportional to size sampling). Further arguments of
method may be supplied as a list via the slot dots.Extends
