Installation

From CRAN

You can install the latest stable version of fastml from CRAN using:

install.packages("fastml")

From GitHub

For the development version, install directly from GitHub using the devtools package:

# Install devtools if you haven't already
install.packages("devtools")

# Install fastml from GitHub
devtools::install_github("selcukorkmaz/fastml")

Quick Start

Here’s a simple workflow to get you started with fastml:

library(fastml)

# Example dataset
data(iris)
iris <- iris[iris$Species != "setosa", ]  # Binary classification
iris$Species <- factor(iris$Species)

# Train models
model <- fastml(
  data = iris,
  label = "Species"
)

# View model summary
summary(model)
