Package-level gigs options

Source: R/gigs_options.R
dot-gigs_options.Rd

An environment containing seven named character vectors. The first six define how gigs handles input data with missing, undefined, or invalid elements. The last ("handle_unused_levels")

  • "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 of x variables which are out of bounds for the standard in use?

  • "handle_invalid_sex" - How should gigs handle elements of sex which are not one of "M" or "F"?

  • "handle_oob_centiles" - In centile2value functions, how should gigs handle elements of p that are not between 0 and 1?

  • "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 to NA, silently.

  • "warn" - Invalid elements are set to NA, 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().

Value

A named environment, where each name maps onto a specific gigs option.
