Generic Function for Interpretation

Interpret a value based on a set of rules. See rules().

Usage

interpret(x, ...)

# S3 method for class 'numeric'
interpret(x, rules, name = attr(rules, "rule_name"), transform = NULL, ...)

# S3 method for class 'effectsize_table'
interpret(x, rules, transform = NULL, ...)

Arguments

x

Vector of value break points (edges defining categories), or a data frame of class effectsize_table.

...

Currently not used.

rules

Set of rules(). When x is a data frame, can be a name of an established set of rules.

name

Name of the set of rules (will be printed).

transform

a function (or name of a function) to apply to x before interpreting. See examples.

Value

• For numeric input: A character vector of interpretations.

• For data frames: the x input with an additional Interpretation column.
