Serialise a design specification to pretty-printed JSON

Usage

spec_json(spec)

Arguments

spec: A design specification (list), as produced by build_spec().

Value

A length-one character string containing the specification as pretty-printed JSON, the portable artefact that the R and 'Python' packages both consume.

Examples

spec <- build_spec(list(name = "demo", seed = 1, design_kind = "between",
  factor_name = "group", lev1 = "a", lev2 = "b", n_subject = 20,
  intercept = 0, effect = 0.5, family = "gaussian", resp_name = "", sigma = 1))
cat(spec_json(spec))
