read_envi: Read ENVI data

In OpenSpecy: Analyze, Process, Identify, and Share Raman and (FT)IR Spectra

Read ENVI data

Description

This function allows ENVI data import.

Usage

read_envi(
  file,
  header = NULL,
  share = NULL,
  metadata = list(file_name = basename(file), user_name = NULL, contact_info = NULL,
    organization = NULL, citation = NULL, spectrum_type = NULL, spectrum_identity = NULL,
    material_form = NULL, material_phase = NULL, material_producer = NULL,
    material_purity = NULL, material_quality = NULL, material_color = NULL,
    material_other = NULL, cas_number = NULL, instrument_used = NULL,
    instrument_accessories = NULL, instrument_mode = NULL, spectral_resolution = NULL,
    laser_light_used = NULL, number_of_accumulations = NULL, 
    
    total_acquisition_time_s = NULL, data_processing_procedure = NULL,
    level_of_confidence_in_identification = NULL, other_info = NULL, license =
    "CC BY-NC"),
  ...
)

Arguments

file	name of the binary file.
header	name of the ASCII header file. If NULL, the name of the header file is guessed by looking for a second file with the same basename as file but with .hdr extension.
share	defaults to NULL; needed to share spectra with the Open Specy community; see share_spec() for details.
metadata	a named list of the metadata; see as_OpenSpecy() for details.
...	further arguments passed to the submethods.

Details

ENVI data usually consists of two files, an ASCII header and a binary data file. The header contains all information necessary for correctly reading the binary file via read.ENVI().

Value

An OpenSpecy object.
