PKNCA (version 0.11.0)

pk.business: 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)

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.

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).

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)))
