read_licor_prn: Read '.PRN' File(s) Saved by LI-COR's PC1800 Program.

Description

Reads and parses the header of a processed data file as output by the PC1800 program to extract the whole header remark field and also check whether data is in photon or energy based units. The time field is ignored as it does not contain year information.

Usage

read_licor_prn(file, date = NULL, geocode = NULL, label = NULL, tz = NULL, locale = readr::default_locale())
read_m_licor_prn(files, date = NULL, geocode = NULL, label = NULL, tz = Sys.timezone(location = FALSE), locale = readr::default_locale())

Arguments

file

Path to file as a character string.

date

a POSIXct object, but if NULL the date stored in file is used, and if NA no date variable is added.

geocode

A data frame with columns lon and lat.

label

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

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.

files

A list or vector of character strings.

Value

read_licor_prn() returns a source_spct object with time.unit attribute set to "second" and when.measured attribute set to the date-time extracted from the file name, or supplied.Function read_m_licor_prn() returns a source_mspct object containing one spectrum per file read.

Details

Function read_m_licor_prn() calls red_licor_file() for each file in files. See read_table for a description of valid arguments for files.
