我们在这里可以使用geom_texthline, geom_textvline, geom_textabline来进行各种阈值线的绘制. dat2 %>% ggplot(aes(Sepal.Length, Sepal.Width)) + geom_point() + geom_texthline(yintercept = 3, label = "hline", hjust = 0.8, color = "red4") + geom_textvline(xintercept = 6, label ...
For the special case ofgeom_sf, which draws different shapes based on the geometry objects drawn, the equivalentgeom_textsfandgeom_labelsf, will identify and label the linestring components (typically rivers and roads), without attempting to label polygons. geom_textlineandgeom_labelline You can...
