Description
Summary:
In the past rstan was able to import bzip2 compressed csv files with the read_stan_csv function. This functionality was dropped in one of the later releases of rstan.
On cluster environments where csv files are stored on network attached storages it is often faster to operate on compressed files due to the smaller io footprint.
Description:
It would be great to have the possibility again to import cmdstan runs results which were compressed with bzip2.
Reproducible Steps:
Current Output:
Expected Output:
RStan Version:
2.19.2
R Version:
3.6.2
Operating System:
macOS Catalina

Research direction
No file or test is named. Start by locating the read_stan_csv entry point and checking how it currently opens CmdStan CSV results; compare that path with the previously supported bzip2 behavior. Done means bzip2-compressed run-result CSV files can be imported again, with coverage for that input.
