Read an ADP data file, producing an adp
object, i.e. one inheriting
from adp-class
.
read.adp(file, from, to, by, tz = getOption("oceTz"), longitude = NA,
latitude = NA, manufacturer = c("rdi", "nortek", "sontek"),
monitor = FALSE, despike = FALSE, processingLog,
debug = getOption("oceDebug"), ...)
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.)
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.
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.
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”.)
character string indicating time zone to be assumed in the data.
optional signed number indicating the longitude in degrees East.
optional signed number indicating the latitude in degrees North.
a character string indicating the manufacturer, used by
the general function read.adp
to select a subsidiary function to use,
such as read.adp.nortek
.
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
.
if TRUE
, despike
will be used to clean
anomalous spikes in heading, etc.
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.)
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.
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).
Several file types can be handled. Some of
these functions are wrappers that map to device names, e.g.
read.aquadoppProfiler
does its work by calling
read.adp.nortek
; in this context, it is worth noting that the
``aquadopp'' instrument is a one-cell profiler that might just as well have
been documented under the heading read.adv
.
