stat_wb_total
computes integral under a curve. Sets suitable default
aesthetics for "rect", "hline", "vline", "text" and "label" geoms displaying
"totals" per waveband. x
-scale transformations and axis
flipping are currently not supported.

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 |
position |
The position adjustment to use for overlapping points on this layer |
... |
other arguments passed on to |
w.band |
a waveband object or a list of waveband objects or numeric vector of at least length two. |
integral.fun |
function on $x$ and $y$. |
label.mult |
numeric Scaling factor applied to y-integral values before conversion into character strings. |
chroma.type |
character one of "CMF" (color matching function) or "CC"
(color coordinates) or a |
label.fmt |
character string giving a format definition for converting
y-integral values into character strings by means of function
|
ypos.mult |
numeric Multiplier constant used to scale returned
|
ypos.fixed |
numeric If not |
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 |
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.
What it is named integral below is the result of appying integral.fun
,
with default integrate_xy
.
ymean multiplied by label.mult
and formatted
according to label.fmt
w.band-midpoint
w.band minimum
w.band maximum
data$y minimum
data$y maximum
data$y integral for the range of w.band
yint divided by wl_expanse(w.band)
ypos.fixed or top of data, adjusted by ypos.mult
color of the w.band
label of w.band
black_or_white(wb.color)
Set by the statistic and available to geoms.
..y.label..
..x..
..wb.xmin..
..wb.xmax..
..y.. - (..wb.ymax.. - ..wb.ymin..) * 0.03
..y.. + (..wb.ymax.. - ..wb.ymin..) * 0.03
..wb.ymean..
..wb.color..
Required by the statistic and need to be set with aes()
.
numeric, wavelength in nanometres
numeric, a spectral quantity
