glmx: Interfaces for glmx package for data science pipelines.

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

Description

Interfaces to glmx functions that can be used in a pipeline implemented by magrittr.

Usage

ntbt_glmx(data, ...)
ntbt_hetglm(data, ...)

Arguments

data	data frame, tibble, list, ...
...	Other arguments passed to the corresponding interfaced function.

Details

Interfaces call their corresponding interfaced function.

Value

Object returned by interfaced function.

Examples

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

## ntbt_glmx: Generalized Linear Models with Extra Parameters
set.seed(1)
d <- data.frame(x = runif(200, -1, 1))
d$y <- rnbinom(200, mu = exp(0 + 3 * d$x), size = 1)
require("MASS")

## Original function to interface
glmx(y ~ x, data = d, family = negative.binomial, xlink = "log", xstart = 0)

## The interface puts data as first parameter
ntbt_glmx(d, y ~ x, family = negative.binomial, xlink = "log", xstart = 0)

## so it can be used easily in a pipeline.
d %>%
  ntbt_glmx(y ~ x, family = negative.binomial, xlink = "log", xstart = 0)


## ntbt_hetglm: Heteroskedastic Binary Response GLMs
n <- 200
x <- rnorm(n)
ystar <- 1 + x +  rnorm(n, sd = exp(x))
y  <- factor(ystar > 0) 
dta <- data.frame(x, y)

## Original function to interface
hetglm(y ~ x | 1, data = dta)

## The interface puts data as first parameter
ntbt_hetglm(dta, y ~ x | 1)

## so it can be used easily in a pipeline.
dta %>%
  ntbt_hetglm(y ~ x | 1)

## End(Not run)
