stat_wl_summary
computes the area under a curve.
Usage
stat_wl_summary(
mapping = NULL,
data = NULL,
geom = "text",
position = "identity",
...,
range = NULL,
integral.fun = integrate_xy,
label.fmt = "%.3g",
na.rm = FALSE,
show.legend = NA,
inherit.aes = TRUE
)
Arguments
- mapping
The aesthetic mapping, usually constructed with
aes
oraes_
. Only needs to be set at the layer level if you are overriding the plot defaults.- data
A layer specific dataset - only needed if you want to override the plot defaults.
- geom
The geometric object to use display the data
- position
The position adjustment to use for overlapping points on this layer
- ...
other arguments passed on to
layer
. This can include aesthetics whose values you want to set, not map. Seelayer
for more details.- range
a numeric vector of at least length two.
- integral.fun
function on $x$ and $y$.
- label.fmt
character string giving a format definition for converting y-integral values into character strings by means of function
sprintf
.- na.rm
a logical value indicating whether NA values should be stripped before the computation proceeds.
- show.legend
logical. Should this layer be included in the legends?
NA
, the default, includes if any aesthetics are mapped.FALSE
never includes, andTRUE
always includes.- inherit.aes
If
FALSE
, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g.borders
.
Computed variables
What it is named integral below is the result of appying integral.fun
,
with default integrate_xy
.
- y.label
y formatted according to
label.fmt
- x
range-midpoint
- wb.xmin
range minimum
- wb.xmax
range maximum
- y
data$y integral for the range by the expanse of the range
Default aesthetics
Set by the statistic and available to geoms.
- label
..label..
- x
..x..
- xmin
..wb.xmin..
- xmax
..wb.xmax..
- y
..y..
- ymin

- ymax

Required aesthetics
Required by the statistic and need to be set with aes()
.
- x
numeric, wavelength in nanometres
- y
numeric, a spectral quantity
