gf_area | R Documentation |
For each x value, geom_ribbon()
displays a y interval defined
by ymin
and ymax
. geom_area()
is a special case of
geom_ribbon()
, where the ymin
is fixed to 0 and y
is used instead
of ymax
.

object |
When chaining, this holds an object produced in the earlier portions of the chain. Most users can safely ignore this argument. See details and examples. |
gformula |

data |
The data to be displayed in this layer. There are three options: If A A |
... |
Additional arguments. Typically these are

alpha |
Opacity (0 = invisible, 1 = opaque). |
color |

fill |

group |
Used for grouping. |
linetype |
A linetype (numeric or "dashed", "dotted", etc.) or a formula used for mapping linetype. |
size |
A numeric size or a formula used for mapping size. |
xlab |
Label for x-axis. See also |
ylab |
Label for y-axis. See also |
title, subtitle, caption |
Title, sub-title, and caption for the plot.
See also |
geom |
A character string naming the geom used to make the layer. |
stat |
The statistical transformation to use on the data for this layer, as a string. |
position |
Position adjustment, either as a string, or the result of a call to a position adjustment function. |
show.legend |
logical. Should this layer be included in the legends?
|
show.help |
If |
inherit |
