rspec2mspct: Convert "pavo::rspec" objects

Description

Convert between 'pavo::rspec' objects containing spectral reflectance data into spectral objects (xxxx_spct, xxxx_mspct) as defined in package 'photobiology'.

Usage

rspec2mspct(
  x,
  member.class = "reflector_spct",
  spct.data.var = "Rpc",
  multiplier = 1,
  ...
)
rspec2spct(x, multiplier = 1, ...)

Arguments

x

rspec object

member.class

character One of the spectrum classes defined in package 'photobiology'.

spct.data.var

character The name to be used for the 'spc' data when constructing the spectral objects.

multiplier

numeric A multiplier to be applied to the 'rspc' data to do unit or scale conversion.

...

currently ignored.

Warning!

Always check the sanity of the imported or exported data values, as guessing is needed when matching the different classes, and the functions defined here are NOT guaranteed to return valid data wihtout help from the user through optional function arguments.

Examples

# example run only if 'pavo' is available
if (requireNamespace("pavo", quietly = TRUE)) {
  library(pavo)
  data(sicalis, package = "pavo")
  sicalis.mspct <- rspec2mspct(sicalis)
  class(sicalis.mspct)

  data(teal, package = "pavo")
  teal.spct <- rspec2spct(teal)
  class(teal.spct)
  levels(teal.spct[["spct.idx"]])
  angles <- seq(from = 15, to = 75, by = 5) # from teal's documentation
  teal.spct[["angle"]] <- angles[as.numeric(teal.spct[["spct.idx"]])]
  teal.spct
