adpRdiFileTrim: Trim an RDI adp File

Description

Create an RDI adp file by copying the first n data chunks (starting with byte 0x7f 0x7f) of another such file. This can be useful in supplying small sample files for bug reports.

Usage

adpRdiFileTrim(infile, n = 100L, outfile, debug = getOption("oceDebug"))

Value

adpRdiFileTrim() returns the name of the output file, outfile, as provided or constructed.

Arguments

infile

name of an RDI file.

n

integer indicating the number of data chunks to keep. The default is to keep 100 chunks, a common choice for sample files.

outfile

optional name of the new RDI 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 "a.000" then outfile will be a_trimmed.000.

debug

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.
