Interactive 3D Surface Plots for Multi-Factor Interaction Visualization R package ixsurface version 0.1.0 Visualize interactions between multiple experimental factors using interactive 3D surface plots powered by 'plotly'. Instead of examining combinatorial pairwise interaction plots, map factor combinations to response surfaces and use surface crossings as geometric indicators of interaction effects. Supports continuous, categorical, and mixed factor designs with automatic binning for continuous conditioning variables. Software Imports: plotly (>= 4.10.0), stats, utils, grDevices Suggests: testthat (>= 3.0.0), knitr, rmarkdown Chris Brantner <cjbrantn@gmail.com> Comprehensive R Archive Network (CRAN) Chris Brantner [aut, cre] MIT + file LICENSE (https://CRAN.R-project.org/package=ixsurface/LICENSE) 2026-03-26 application/tgz https://CRAN.R-project.org/package=ixsurface doi:10.32614/CRAN.package.ixsurface
