read_avaspec_csv: Read '.csv' File Saved by Avantes' Software for AvaSpec.

Description

Reads and parses the header of a processed data file as output by the program Avaspec and then imports wavelength and spectral irradiance values. The file header has little useful metadata information.

Usage

read_avaspec_csv(
  file,
  date = NULL,
  geocode = NULL,
  label = NULL,
  tz = NULL,
  locale = readr::default_locale()
)
read_avaspec_xls(
  path,
  date = NULL,
  geocode = NULL,
  label = NULL,
  tz = NULL,
  locale = readr::default_locale()
)

Value

A source_spct object.

Arguments

file

character string

date

a POSIXct object to use to set the "when.measured" attribute. If NULL, the default, the date is extracted from the file header.

geocode

A data frame with columns lon and lat used to set attribute "where.measured".

label

character string, but if NULL the value of file is used, and if NA the "what.measured" attribute is not set.

tz

character Time zone used for interpreting times saved in the file header.

locale

The locale controls defaults that vary from place to place. The default locale is US-centric (like R), but you can use locale to create your own locale that controls things like the default time zone, encoding, decimal mark, big mark, and day/month names.

path

Path to the xls/xlsx file
