Load configurations from a config file into the movenet environment

load_config() checks that the provided configfile is valid, and then loads its content into the movenet environment. This lets the movenet package know how to read and interpret upcoming input data files.

Usage

load_config(configfile)

Arguments

configfile

Either the path to a YAML-format movenet config file, or the name of a pre-installed config file in the movenet package's configurations folder.

Value

No return value, but load_config() has the effect of copying the provided configurations into the movenet environment. If this is successful, a message is printed.

Details

Values of configurations representing column headers or indices (in the config file fileopts section) are converted to ASCII-compliant and syntactically valid names before being loaded into in the environment.
