Run C++ simulation.

A result is first written to a directory in cache, and then read into a data.frame. If a previous result with exactly the same arguments is found in cache, it is read without calling tekka.

Usage

tekka(args = character(0L), cache = NULL)

Arguments

args

Command line arguments as a string vector. See tekka manual and tekka("--help") for available options. Note that a random --seed is appended if not given. Use set.seed() or --seed explicitly for reproducibility and caching.

cache

Parent directory for tekka output. TRUE is equivalent to "." (current directory). tempdir() is used in other cases including the default (NULL), which is discarded at the end of an R session. Set FALSE to force tekka to run and overwrite previous results if any.
