stat_wb_label
computes computes the center of a waveband. Sets
suitable default aesthetics for "text" and "label"
geoms displaying "boundaries" and "names" of wavebands.
stat_wb_label(
mapping = NULL,
data = NULL,
geom = "text",
w.band = NULL,
chroma.type = "CMF",
label.fmt = "%s",
ypos.fixed = 0,
position = "identity",
na.rm = TRUE,
show.legend = NA,
inherit.aes = TRUE,
...
)
mapping |
The aesthetic mapping, usually constructed with
|
data |
A layer specific dataset - only needed if you want to override the plot defaults. |
geom |
The geometric object to use display the data |
w.band |
a waveband object or a list of waveband objects or numeric vector of at least length two. |
chroma.type |
character one of "CMF" (color matching function) or "CC"
(color coordinates) or a |
label.fmt |
character string giving a format definition for formating
the name of the waveband.
|
ypos.fixed |
numeric If not |
position |
The position adjustment to use for overlapping points on this layer |
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?
|
inherit.aes |
If |
... |
other arguments passed on to |
A data frame with one row for each waveband object in the argument
to w.band
. Wavebeand outside the range of the spectral data are
trimmed or discarded.
w.band-midpoint
w.band minimum
w.band maximum
ypos.fixed or zero
color of the w.band
label of w.band
formatted wb.name
Set by the statistic and available to geoms.
..wb.label..
..x..
..wb.xmin..
..wb.xmax..
..wb.color..
Required by the statistic and need to be set with aes()
.
numeric, wavelength in nanometres
This stat uses a panel function and ignores grouping as it is meant to be used for annotations.
