Labeling facets
If your factor levels are not clear, your facet labels may be confusing. You can assign proper labels in your original data before plotting (see next exercise), or you can use the labeller
argument in the facet layer.
The default value is
label_value
: Default, displays only the value
Common alternatives are:
label_both
: Displays both the value and the variable namelabel_context
: Displays only the values or both the values and variables depending on whether multiple factors are faceted
