decodeHeaderNortek {oce} | R Documentation |
Decode data in a Nortek ADV or ADP header.
decodeHeaderNortek(buf, type = c("aquadoppHR", "aquadoppProfiler", "aquadopp", "vector"), debug = getOption("oceDebug"), ...)
buf |
a “raw” buffer containing the header |
type |
type of device |
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. |
Decodes the header in a binary-format Nortek ADV/ADP file. This function is
designed to be used by read.adp
and read.adv
,
but can be used directly as well. The 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 authorative 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 list containing elements hardware
, head
, user
and offset
. The easiest way to find the contents of these is to run
this function with debug=3
.

1. Information on Nortek profilers (including the System Integrator Guide, which explains the data format byte-by-byte) is available at http://www.nortekusa.com/. (One must join the site to see the manuals.)
2. The Nortek Knowledge Center http://www.nortekusa.com/en/knowledge-center may be of help if problems arise in dealing with data from Nortek instruments.
Most users should employ the functions read.adp
and
read.adv
instead of this one.
