read.adp.ad2cp() cannot handle datatype 0x30 ("processed wave data record")

[dankelley]

[dankelley]

The docs now mention this dataType value, but say it is not handled yet. Also, the code will detect this, and report an error if it's found.

This data type is described in pages 98 to 106 of Ref 1. That's a lot of information! There's no point in trying to code all of that stuff in to oce without a test dataset and, ideally, a user who really needs this and can interact with us to help to debug any code that gets written. Therefore I am labelling this as a 'low priority' item.

@richardsc - I wonder if you have an ad2cp file with datatype 0x30? This issue has been silent for a long time, and if we try for a CRAN release in the first few months of 2026, it might be nice to have this one cleared. I do have the docs, but I'm reluctant to try typing in a lot of code that cannot be tested or checked, for lack of a sample file (and a user with an interest in such data).

I could plug away on this over the holidays.

I don't think I do, unfortunately. It might be worth asking Nortek if they have an example file (they have provided similar for me in the past, e.g. relating to ice draft measurements)

[dankelley]

If we got a file - and if any nortek software that's available can read it so we can check - I could go ahead.

One caveat though -- I remember a while back we coded some stuff but they changed the file format from what was said in the docs. I can see how this would happen for new data types, where the documenter might start by doing copy-past operations from similar data types.

[dankelley]

For reference, I'm attaching some of the relevant pages from the nortek manual. This is a complicated format (spanning 9 pages in the nortek docs), and I don't think there is much chance of coding it quickly. I don't want to hold up a CRAN release for this. The priority would be higher if a Dal/BIO person needed to read such a file and lacked other tools to do so.
