interaction-plot

interaction_plot

Plots the mean of the response for
two-way combinations of factors, thereby illustrating possible
interactions.

Utility package containing:
1) Facilities for working with grouped data: 'do' something to data
stratified 'by' some variables.
2) LSmeans (least-squares means), general linear estimates.
3) Restrict functions to a smaller domain.
4) Miscellaneous other utilities.
