Two problems with writeGDX function #10

Open joanna-sitarz opened 3 weeks ago

joanna-sitarz commented 3 weeks ago

Issue 1) writeGDX() runs into an error when the data I am trying to write was previously read in using "restore_zeros = FALSE", format="simplest".

"Error in if (out$type == "set") { : argument is of length zero"

The error does not occur if restore_zeros = TRUE. However I am running into memory problems when I set it to TRUE.

Issue 2) writeGDX() changes some underlying information about data if the data is in the format "raw".

If my variable I am reading/writing into gdx has 0 records information about sets gets removed during the process of writing the gdx.

I am attaching a folder with very simple code demonstrating the issues 1 and 2. WriteGDXProblem.zip

@joanna-sitarz sorry for the very late response. the gdx package is relying on the gdxrrw package of the GAMS team which is deprecated, which is why we also moved from gdx to gdx2 which is now based on the new GAMS packages gamstransfer. gdx2 does not provide a writeGDX functionality anymore, but gamstransfer itself does. Can you perhaps have a look whether this can help you here?
