## 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", package = "flexmix")
    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)
