read.adp.sontek: Read a Sontek ADP File

Description

Read a Sontek acoustic-Doppler profiler file [1].

Usage

read.adp.sontek(file, from = 1, to, by = 1, tz = getOption("oceTz"),
  longitude = NA, latitude = NA, type = c("adp", "pcadp"),
  monitor = FALSE, despike = FALSE, processingLog,
  debug = getOption("oceDebug"), ...)

Arguments

file

a connection or a character string giving the name of the file to load. (For read.adp.sontek.serial, this is generally a list of files, which will be concatenated.)

from

indication of the first profile to read. This can be an integer, the sequence number of the first profile to read, or a POSIXt time before which profiles should be skipped, or a character string that converts to a POSIXt time (assuming UTC timezone). See “Examples”, and make careful note of the use of the tz argument. If from is not supplied, it defaults to 1.

to

an optional indication of the last profile to read, in a format as described for from. As a special case, to=0 means to read the file to the end. If to is not supplied, then it defaults to 0.

by

an optional indication of the stride length to use while walking through the file. If this is an integer, then by-1 profiles are skipped between each pair of profiles that is read, e.g. the default by=1 means to read all the data. (For RDI files only, there are some extra features to avoid running out of memory; see “Memory considerations”.)

tz

character string indicating time zone to be assumed in the data.

longitude

optional signed number indicating the longitude in degrees East.

latitude

optional signed number indicating the latitude in degrees North.

type

A character string indicating the type of instrument.

monitor

boolean, set to TRUE to provide an indication of progress in reading the file, either by printing a dot for each profile or by writing a textual progress bar with txtProgressBar.

despike

if TRUE, despike will be used to clean anomalous spikes in heading, etc.

processingLog

if provided, the action item to be stored in the log. (Typically only provided for internal calls; the default that it provides is better for normal calls by a user.)

debug

a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more.

additional arguments, passed to called routines.

Value

An adp object, i.e. one inheriting from adp-class. The form of this object varies with instrument type. In some cases navigational data may be included, e.g. read.adp.rdi can read NMEA strings (which get stored in an item called nmea in the data slot).
