Interactive 3D scatterplot with a fitted regression plane

Build an interactive 3D scatterplot of an outcome against two numeric predictors, overlaid with the fitted plane from lm(formula, data). Returns a plotly htmlwidget that you can render in an R Markdown / Quarto document or in the RStudio Viewer.

Usage

plot_3d_regression(data, formula, n = 25)

Arguments

data

a data frame containing the three variables in formula.

formula

a formula of the form z ~ x + y: a single outcome on the left-hand side and exactly two predictor variables on the right-hand side. In-formula transformations (e.g. log(z) ~ x + y) are not supported in this version — apply transformations to data beforehand.

n

grid resolution per axis used to draw the regression plane. Default 25.

Value

A plotly htmlwidget object.

Details

Requires the suggested package plotly. Install it with install.packages("plotly") if you see an error about it being missing.
