Methods for Function Lapply

Description

Apply a function to each component of a finite mixture

Usage

## S4 method for signature 'FLXRmstep':
Lapply(object, FUN, model = 1, component = TRUE, ...)

Arguments

object S4 class object.
FUN The function to be applied.
model The model (for a multivariate response) that shall be used.
component Index vector for selecting the components.
... Optional arguments to 'FUN'.

Details

'FUN' is found by a call to 'match.fun' and typically is specified as a function or a symbol (e.g. a backquoted name) or a character string specifying a function to be searched for from the environment of the call to 'Lapply'.

Value

A list of the length equal to the number of components specified is returned, each element of which is the result of applying 'FUN' to the specified component of the refitted mixture model.

Methods

object = FLXRmstep:
Apply a function to each component of a refitted flexmix object using method = "mstep".

Examples

data("NPreg")
ex2 <- flexmix(yn ~ x, data = NPreg, k = 2, model = list(FLXMRglm(yn ~ 
    . + I(x^2)), FLXMRglm(yp ~ ., family = "poisson")))
ex2r <- refit(ex2, method = "mstep")
Lapply(ex2r, "vcov", 2)
