suppfun: Convert various datasets to support functions.

In RobinHankin/hyper2: The Hyperdirichlet Distribution, Mark 2

Convert various datasets to support functions.

Description

Function suppfun() is an S3 generic that returns a support function, dispatching on the class of its primary argument.

Usage

## S3 method for class 'ordertable'
suppfun(x, ...)
## S3 method for class 'ranktable'
suppfun(x, times, ...)
## S3 method for class 'character'
suppfun(x, nonfinishers, ...)
suppfun(x, ...)

Arguments

x	Dataset to be converted to a support function
times	Vector corresponding to rows of x giving how many times that observation was obtained (cf preflib datasets); recycled if necessary
nonfinishers	Character vector of competitors who did not finish, passed to rankvec_likelihood()
...	Further arguments

Details

Function suppfun() is intended as a consistent S3 generic approach to converting datasets to support functions. I am gradually going to switch out use of ordertable2supp() in favour of suppfun() in the docs.

If given a data frame, suppfun() will not guess whether it is to be interpreted as an ordertable or a ranktable, and return an error.

Value

Generally, return a support function

suppfun(rrank(10, p = (7:1)/28))
suppfun(letters)
suppfun(c(c = 2, b = 1, a = 3))
