In intubate: Interface to Popular R Functions for Data Science Pipelines

ntbt_flexmix(data, ...)
ntbt_initFlexmix(data, ...)

Object returned by interfaced function.

Examples

## Not run: 
library(intubate)
library(magrittr)
library(flexmix)


## ntbt_flexmix: Flexible Mixture Modeling
data("NPreg", package = "flexmix")

## Original function to interface
set.seed(1)
ex1 <- flexmix(yn ~ x + I(x^2), data = NPreg, k = 2,
               control = list(verb = 5, iter = 100))
plot(ex1)

## The interface puts data as first parameter
set.seed(1)
ex1 <- ntbt_flexmix(NPreg, yn ~ x + I(x^2), k = 2,
                    control = list(verb = 5, iter = 100))
plot(ex1)

## so it can be used easily in a pipeline.
set.seed(1)
NPreg %>%
  ntbt_flexmix(yn ~ x + I(x^2), k = 2,
               control = list(verb = 5, iter = 100)) %>%
  plot()

## NOTE: it seems we could also add initFlexmix and stepFlexmix,
##       that call flexmix repeteadly. I will not include examples
##       for those for now.

## End(Not run)
