Command Reference
Below is 1) a list of command domains, and 2) a full list of all commands.
The pages that are linked to describe the Luna command language, which can be used either via the terminal-based lunaC tool or the R extension library lunaR. Under each section, we tabulate the relevant commands, along with their input parameters and output variables. We give examples using a mixture of lunaC and lunaR; also see lunaC's help function.
