pk.business: Run any function with a maximum missing fraction of X and 0s...

In billdenney/pknca: Perform Pharmacokinetic Non-Compartmental Analysis

Run any function with a maximum missing fraction of X and 0s possibly counting as missing. The maximum fraction missing comes from PKNCA.options("max.missing").

Description

Note that all missing values are removed prior to calling the function.

Usage

pk.business(FUN, zero.missing = FALSE, max.missing)

Arguments

FUN	function to run. The function is called as FUN(x, ...) with missing values removed.
zero.missing	Are zeros counted as missing? If TRUE then include them in the missing count.
max.missing	The maximum fraction of the data allowed to be missing (a number between 0 and 1, inclusive).

Value

A version of FUN that can be called with parameters that are checked for missingness (and zeros) with missing (and zeros) removed before the call. If max.missing is exceeded, then NA is returned.

Examples

my_mean <- pk.business(FUN=mean)
mean(c(1:3, NA))
# Less than half missing results in the summary statistic of the available
# values.
my_mean(c(1:3, NA))
# More than half missing results in a missing value
my_mean(c(1:3, rep(NA, 4)))
