process_solution not working with PLEXOS v8.2R01

[jennielu92]

process_solution does not seem to work with the newest version of PLEXOS, v8.2R01. I get this error:

Error: $ operator not defined for this S4 class

In debugging with the source code, it seems like it originates in the function correct_length() although I'm not sure if that's the only issue, or just the first one.

Not sure it's advisable, but I turned off the correct_length() check and now got this error:

Error: Problem reading interval binary data (reached end of file). 720 values requested, 390 returned. This is likely a bug in rplexos. Please report it.

I had this same issue, but this repository hasn't been pushed to since 2017 so...... Please post here if you find a solution though!

Hey @jennielu92 and @samjohnson12, we encountered the same issue and I'm not sure what the package's original developer, @eibanez is up to these days, so I cloned this repo and rewrote its query functions to query HDF5 databases created in Julia using NREL/H5PLEXOS.jl instead of SQLite databases. This allows us to a) access solutions created with PLEXOS v8.2 and higher and b) access the same databases from R as we do from Python (where we use h5plexos).

If you want to check it out and give it a shot, it's the h5plexos branch here.

Just a note that it's still under development, but we've successfully been using it for a few projects at NREL for the past six months or so.

Thanks @mattirish, I was able to find a fix by rolling back to an earlier version of PLEXOS but I'll pass this on to a colleague who is still using PLEXOS. Glad to hear there's an updated solution!

Hi @mattirish, I'll be trying this out soon! Thanks for the heads up on this.
