coef,oscar-method {oscar}

Extract coefficients of oscar-objects

Description

Extract coefficients of oscar-objects

Prediction based on oscar-objects

Plot oscar-coefficients as a function of k and override default plot generic

Usage

## S4 method for signature 'oscar'
coef(object, k)

## S4 method for signature 'oscar'
predict(
  object,
  k,
  type = c("response", "link", "nonzero", "coefficients", "label"),
  newdata = object@x
)

## S4 method for signature 'oscar'
plot(x, y, k = 1:x@kmax, add = FALSE, intercept = FALSE, ...)

Arguments

object

Fit oscar S4-object

k

Vector of cardinality 'k' values

type

Type of prediction; valid values are 'response', 'link', 'nonzero', 'coefficients', or 'label'

newdata

Data to predict on; if no alternate is supplied, the function uses the original 'x' data matrix used to fit object

x

Values on x-axis

y

Values on y-axis

add

Should the plot be added on top of an existing plot (if FALSE, create a new graphics device), Default: FALSE

intercept

Should model intercept be plotted, Default: FALSE

...

Additional parameters passed on to the points-function drawing lines as a function of cardinality

Value

Vector of model coefficient values at given cardinality 'k'

A vector of coefficient predictions at the specificied cardinality 'k' with a format depending on the supplied 'type' parameter

Override default plot function with no return but instead tailor suitable graphics plotting
