read_csi_dat

R Documentation

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

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

read_csi_dat(
  file,
  geocode = NULL,
  label = NULL,
  data_skip = 0,
  n_max = Inf,
  locale = readr::default_locale(),
  na = c("", "NA", "NAN"),
  ...
)

Arguments

`file`	Path to file as a character string.
`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.
`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.
`na`	character Vector of strings to interpret as missing values. Set this option to character() to indicate no missing values.
`...`	Further named arguments currently passed to `read_csv()`.

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.
