The goal of geomtextpath is to label (curved) lines in a plot. The ggplot2 package has various ways to construct lines. For several of the ggplot2 line functions, there is a plain 'text' sibling and a 'label' sibling that includes a text box. Below is an overview of how function in geomtextpath relate to those in ggplot2.
| ggplot2 geom | Text equivalent | Label equivalent |
geom_path() | geom_textpath() | geom_labelpath() |
geom_line() | geom_textline() | geom_labelline() |
geom_segment() | geom_textsegment() | geom_labelsegment() |
geom_curve() | geom_textcurve | geom_labelcurve() |
geom_abline() | geom_textabline() | geom_labelabline() |
geom_hline() | geom_texthline() | geom_labelhline() |
geom_vline() | geom_textvline() | geom_labelvline() |
geom_density() | geom_textdensity() | geom_labeldensity() |
geom_smooth() | geom_textsmooth() | geom_labelsmooth() |
geom_contour() | geom_textcontour() | geom_labelcontour() |
geom_density2d() | geom_textdensity2d() | geom_labeldensity2d() |
geom_sf() | geom_textsf() | geom_labelsf() |
