## S3 method for class 'object_spct'
plot(x, ...,
  w.band = getOption("photobiology.plot.bands", default = list(UVC(), UVB(),
  UVA(), PAR())), range = NULL, plot.qty = "all", pc.out = FALSE,
  label.qty = NULL, span = 61, annotations = NULL, stacked = TRUE,
  text.size = 2.5, na.rm = TRUE)

Arguments

x

an object_spct object

...

other arguments passed along, such as label.qty

w.band

a single waveband object or a list of waveband objects

range

an R object on which range() returns a vector of length 2, with min annd max wavelengths (nm)

plot.qty

character string, one of "all", "transmittance", "absorbance", "absorptance", or "reflectance".

pc.out

logical, if TRUE use percents instead of fraction of one

label.qty

character string giving the type of summary quantity to use for labels, one of "mean", "total", "contribution", and "relative".

span

a peak is defined as an element in a sequence which is greater than all other elements within a window of width span centered at that element.

annotations

a character vector

stacked

logical

text.size

numeric size of text in the plot decorations.

na.rm

logical.

Value

a ggplot object.

Note

The ggplot object returned can be further manipulated and added to. Except when no annotations are added, limits are set for the x-axis and y-axis scales. The y scale limits are expanded to include all data, or at least to the range of expected values. Scales are further expanded so as to make space for the annotations.
