Create a Sontek ADR adv (acoustic Doppler velocimeter) file by copying the
header plus the first n data chunks (recognized by the three-byte sequence
0xA5, 0x11, `0x3c') into a new file. This can be useful in supplying
small sample files for bug reports.
advSontekAdrFileTrim(infile, n = 100, outfile, debug = getOption("oceDebug"))advSontekAdrFileTrim() returns the name of the output file, outfile, as
provided or constructed.
name of a Sontek ADR adp file.
integer indicating the number of data chunks to keep. The default is to keep 100 chunks, a common choice for sample files.
optional name of the new Sontek ADR adp file to be created. If this is not
supplied, a default is used, by adding _trimmed to the base filename, e.g.
if infile is "x.adr" then outfile will be x_trimmed.adr.
an integer value indicating the level of debugging. If this is 1L, then a brief indication is given of the processing steps. If it is > 1L, then information is given about each data chunk, which can yield very extensive output.
