# Reference

In this section you can find information about the functions and methods available in the `powerly`

package. The information in this section is grouped in two categories, namely, *functions* and *methods*.

## Functions

This category refers to the user exported functions, i.e., the functions that encapsulate the functionality provided by `powerly`

(e.g., running a sample size analysis). The following functions are currently available and documented:

`generate_model`

: for generating true model parameters`powerly`

: for running a sample size analysis`validate`

: for validating the results of a sample size analysis

## Methods

Methods (i.e., `S3`

) refer to built-in `R`

functions that can operate on the output provided by the functions exported by the `powerly`

package. Two types of `S3`

methods are currently implemented, i.e., `plot`

and `summary`

:

`plot.Method`

: for plotting the results of a sample size analysis`plot.Validation`

: for plotting the results of a sample size analysis validation`summary`

: for summarizing the results of a sample size analysis or validation
