mid.extract() returns a component of a MID model.
Usage
mid.extract(object, component, ...)
mid.encoding.scheme(object, ...)
mid.frames(object, ...)
mid.terms(
object,
main.effect = TRUE,
interaction = TRUE,
require = NULL,
remove = NULL,
...
)
# S3 method for class 'mid'
terms(x, ...)
# S3 method for class 'mid.importance'
terms(x, ...)
# S3 method for class 'mid'
formula(x, ...)
# S3 method for class 'mid'
model.frame(object, ...)Arguments
- object
a "mid" object.
- component
a literal character string or name. The name of the component to extract, such as "frames", "encoding.scheme" and "terms".
- ...
optional parameters to be passed to the function used to extract the component.
- main.effect
logical. If
FALSE, the main effect terms are excluded.- interaction
logical. If
FALSE, the interaction terms are excluded.- require
a character vector of variable names. The terms that are not related to any of the specified names are excluded.
- remove
a character vector of variable names. The terms that are related to at least one of the specified names are excluded.
- x
a "mid" or "mid.importance" object.
Value
mid.extract() returns the component extracted from the object,
mid.encoding.scheme() returns a data frame containing the information about encoding schemes,
mid.frames() returns a list of the encoding frames,
mid.terms() returns a character vector of the term labels, and
