The graphics are designed to answer common scientific questions, in particular those often asked of high throughput genomics data. arrow: Arrow. Again, the ‘canonical’ way of plotting vectors is to use geom_segment() and specify x, y, xend and yend aesthetics which can be a lot of typing when one has the data on location and displacement (or velocity). fill: fill colour to use for the arrow head (if closed). They may also be parameters to the paired geom/stat. reverselog_trans() Reverse log transform. Before ggplot2 introduced geom_contour_filled(), the ‘canonical’ way to get filled contours was by using stat_contour() with a polygon geom and mapping fill to level (see this issue). geom_arrow (mapping = NULL, data = NULL, stat = "arrow", position = "identity",. geom_abline (intercept = 0, slope = 1), then behind the scenes the geom makes a new data frame containing just the data you've supplied. The curvature, angle and ncp arguments of geom_curve are also available: if curvature is set to any value above 0 (the default), the edges.
