An environment containing seven named character vectors. The
first six define how gigs handles input data with missing, undefined,
or invalid elements in input data. The last ("handle_unused_levels")
defines how gigs responds to unused factor levels when performing
growth categorisations.
"handle_missing_data"- How should gigs handle missing (NA) elements?"handle_undefined_data"- How should gigs handle undefined (NaN,Inf,-Inf) elements?"handle_oob_xvar"- How should gigs handle elements ofxvariables which are out of bounds for the standard in use?"handle_invalid_sex"- How should gigs handle elements ofsexwhich are not one of"M"or"F"?"handle_oob_centiles"- Incentile2valuefunctions, how should gigs handle elements ofpthat are not between0and1?"handle_unused_levels"- When generating growth categories as factors, should gigs drop or keep unused factor levels, and should it issue warnings when unused factor levels occur?
Each of the input-checking options can take one of three values:
"quiet"- Invalid elements are set toNA, silently."warn"- Invalid elements are set toNA, with warnings issued when this is done."error"- Invalid elements will cause informative errors.
For "handle_unused_levels", there are four valid choices:
"keep_quiet"- Keep unused factor levels, and don't issue a warning."keep_warn"- Keep unused factor levels, whilst issuing a warning."drop_quiet"- Drop unused factor levels, and don't issue a warning."drop_warn"- Drop unused factor levels, whilst issuing a warning.
You can use gigs_option_set() or gigs_option_set() to change these
options on a one-by-one basis. To change all the input-checking options to
a specific value, use gigs_input_options_set().

The gigs_option_get(), gigs_option_set() and
gigs_input_options_set() functions, which can be used to get and set
values in .gigs_options.
