The parsnip package from tidymodels acts like an aggregator across the various modeling engines within R. Both of these functions will fit a linear regression model to our data with slightly different implementations. The next step in the process is to build a linear regression model object to which we fit our training data.įor every model type, such as linear regression, there are numerous packages (or engines) in R that can be used.įor example, we can use the lm() function from base R or the stan_glm() function from the rstanarm package. Unlike RStudio cloud, this service has no monthly usage limits, but it may take up to 10 minutes to launch and you will not be able to save your work. This will launch a pre-configured RStudio environment within your browser. Please remember to use your GMU e-mail address.Ĭlick the button below to launch an interactive RStudio environment using. Note: you will need to register for an account before opening the project. Please click the button below to open an interactive version of all course R tutorials through RStudio Cloud. Then we will focus on building our first machine learning pipeline, with data resampling, featuring engineering, modeling fitting, and model accuracy assessment using the workflows, rsample, recipes, parsnip, and tune packages from tidymodels. We will start by fitting a linear regression model to the advertising data set that is used throughout chapter 3 of our course textbook, An Introduction to Statistical Learning. In this tutorial, we will learn about linear regression with tidymodels.
