additive supports Generalized Additive Models (GAM) using mgcv with parsnip/tidymodels.

The stable version of additive can be installed from CRAN using:

install.packages("additive")

The development version of additive can be installed from GitHub using:

install.packages("pak")
pak::pkg_install("hsbadr/additive")

library(additive)

set.seed(2020)
dat <- gamSim(1, n = 400, dist = "normal", scale = 2)

additive_mod <-
  additive() |>
  set_engine("mgcv") |>
  fit(
    y ~ s(x0) + s(x1) + s(x2) + s(x3),
    data = dat
  )

summary(additive_mod$fit)
