Check an imputation specification

The specification is resolved the way PKNCAdata() and pk.nca() resolve it: the name of a column in intervals, NA to use the "impute" column of intervals when there is one, or otherwise a string of imputation methods. Every method named must exist.

Usage

assert_impute_method(impute, intervals = data.frame())

Arguments

impute

The imputation specification (a character scalar or NA)

intervals

The intervals data.frame (if the specification may name one of its columns)

Value

The resolved imputation strings (one per interval when read from a column), invisibly, or an error

assert_impute_method(
  "method",
  intervals = data.frame(start = 0, end = 24, method = "start_conc0")
)
try(assert_impute_method("start_misspelled"))
