geom_box | R Documentation |
The geom_box()
function offers a more flexible variant of geom_rect()
and
geom_tile()
. Instead of exclusively working with the (x/y)min
/(x/y)max
or (x/y)
/(width/height)
aesthetics, any two out of these four
aesthetics suffice to define a rectangle.
geom_box( mapping = NULL, data = NULL, stat = "identity", position = "identity", ..., linejoin = "mitre", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE, radius = NULL )

Set of aesthetic mappings created by |

The data to be displayed in this layer. There are three options: If A A |
stat |
The statistical transformation to use on the data for this
layer, either as a |
position |
Position adjustment, either as a string naming the adjustment
(e.g. |

Other arguments passed on to |

Line join style (round, mitre, bevel). |
