Read '.DAT' file(s) saved by modern Campbell Scientific loggers.

Share:

Description

Reads and parses the header of a processed data file as output by the PC400 or PC200W programmes extracting variable names, units and quantities from the header. Uses the comment attribute to store the metadata.

Usage

1
2
read_csi_dat(file, geocode = NULL, label = NULL, data_skip = 0,
  n_max = Inf, locale = readr::default_locale())

Arguments

file

Path to file as a character string.

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.

data_skip

integer Number of records (rows) to skip from the actual data block.

n_max

integer Maximum number of records to read.

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.

Value

read_csi_dat() returns a tibble::tibble object.

Note

This function is not useful for .DAT and .PRN files from old CSI loggers and software. Those were simple files, lacking metadata, which was stored in separate .FLD files.
