Decode table-of-contents file from a rsk file, of the sort used by some researchers at Dalhousie University.
rskToc(dir, from, to, debug = getOption("oceDebug"))
name of a directory containing a single table-of-contents file, with
optional integer to control debugging, with positive values indicating to print information about the processing.
It is assumed that the
.TBL file contains lines of the form
\day179\SL08A179.023 started at Fri Jun 27 22:00:00 2008" The first step is
to parse these lines to get day and hour information, i.e. 179 and 023 in the
line above. Then, recognizing that it is common to change the names of such
files, the rest of the file-name information in the line is ignored, and instead
a new file name is constructed based on the data files that are found in the
directory. (In other words, the
"\\day179\\SL08A" portion of the line is
replaced.) Once the file list is complete, with all times put into R format,
then (optionally) the list is trimmed to the time interval indicated by
to. It is important that
to be in
UTC time zone, because that time zone is used in decoding the lines
A list with two elements:
filename, a vector of file names, and
startTime, a vector of
POSIXct() times indicating the (real)
times of the first datum in the corresponding files.
