Validate a vpc_stats object

Internal helper. Asserts that x carries the vpc_stats class, contains the stats and obs data.frames, and that each carries the column groups downstream consumers (notably plot_build_vpc()) depend on. Aborts with a clear message on failure; returns x invisibly on success.

Usage

validate_vpc_stats(x, arg = rlang::caller_arg(x), call = rlang::caller_env())

Arguments

x

Object to validate.

arg, call

The argument name and call reported in errors.

Value

invisible(x) on success.
