read.aquadoppHR {oce} | R Documentation |
The R code is based on information in the Nortek System Integrator Guide (2008) and on postings on the Nortek “knowledge center” discussion board. One might assume that the latter is less authoritative than the former. For example, the inference of cell size follows advice found at http://www.nortekusa.com/en/knowledge-center/forum/hr-profilers/736804717 (downloaded June 2012)), which contains a typo in an early posting that is corrected later on.

a connection or a character string giving the name of the file

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 |

an optional indication of the last profile to read, in a
format as described for |

an optional indication of the stride length to use while walking through
the file. If this is an integer, then |
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. |
orientation |
Optional character string specifying the orientation of the
sensor, provided for those cases in which it cannot be inferred from the
data file. The valid choices are |
distance |
Optional vector holding the distances of bin centres from the sensor. This argument is ignored except for Nortek profilers, and need not be given if the function determines the distances correctly from the data. The problem is that the distance is poorly documented in the Nortek System Integrator Guide (2008 edition, page 31), so the function must rely on word-of-mouth formulae that do not work in all cases. |
monitor |
boolean, set to |
despike |
if |
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. |
