Collection-of-spectra constructor

Source: R/zmspct.classes.R
generic_mspct.Rd

Converts a list of spectral objects into a "multi spectrum" object by setting the class attribute of the list of spectra to the corresponding multi-spct class, check that components of the list belong to the expected class.

Usage

generic_mspct(
  l = NULL,
  class = "generic_spct",
  ncol = 1,
  byrow = FALSE,
  dim = c(length(l)%/%ncol, ncol)
)

calibration_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

raw_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

cps_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

source_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

filter_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

reflector_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

object_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

solute_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

response_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

chroma_mspct(l = NULL, ncol = 1, byrow = FALSE, ...)

Arguments

l

list of generic_spct or derived classes

class

character The multi spectrum object class or the expected class for the elements of l

ncol

integer Number of 'virtual' columns in data

byrow

logical If ncol > 1 how to read in the data

dim

integer vector of dimensions

...

ignored

Functions

  • calibration_mspct(): Specialization for collections of calibration_spct objects.

  • raw_mspct(): Specialization for collections of raw_spct objects.

  • cps_mspct(): Specialization for collections of cps_spct objects.

  • source_mspct(): Specialization for collections of source_spct objects.

  • filter_mspct(): Specialization for collections of filter_spct objects.

  • reflector_mspct(): Specialization for collections of reflector_spct objects.

  • object_mspct(): Specialization for collections of object_spct objects.

  • solute_mspct(): Specialization for collections of solute_spct objects.

  • response_mspct(): Specialization for collections of response_spct objects.

  • chroma_mspct(): Specialization for collections of chroma_spct objects.

Note

Setting class = source_spct or class = source_mspct makes no difference
