plot.source_spct: Plot methods for light-source spectra.

Description

These methods return a ggplot object with an annotated plot of a source_spct object or of the spectra contained in a source_mspct object.

Usage

# S3 method for source_spct
plot(x, ...,
  w.band = getOption("photobiology.plot.bands", default = list(UVC(),
  UVB(), UVA(), PAR())), range = NULL,
  unit.out = getOption("photobiology.radiation.unit", default =
  "energy"), label.qty = NULL, span = NULL, annotations = NULL,
  time.format = "", tz = "UTC", text.size = 2.5, idfactor = NULL,
  ylim = c(NA, NA), na.rm = TRUE)
# S3 method for source_mspct
plot(x, ..., range = NULL)

Arguments

x

a source_spct or a source_mspct object.

...

in the case of collections of spectra, additional arguments passed to the plot methods for individual spectra, otherwise currently ignored.

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).

unit.out

character string indicating type of radiation units to use for plotting: "photon" or its synomin "quantum", or "energy".

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.

time.format

character Format as accepted by strptime.

tz

character Time zone to use for title and/or subtitle.

text.size

numeric size of text in the plot decorations.

idfactor

character Name of an index column in data holding a factor with each spectrum in a long-form multispectrum object corresponding to a distinct spectrum. If idfactor=NULL the name of the factor is retrieved from metadata or if no metadata found, the default "spct.idx" is tried.

ylim

numeric y axis limits,

na.rm

logical.

Value

a ggplot object.
