exclude: Exclude data points or results from calculations or...

In PKNCA: Perform Pharmacokinetic Non-Compartmental Analysis

Exclude data points or results from calculations or summarization.

Description

Exclude data points or results from calculations or summarization.

Usage

exclude(object, reason, mask, FUN)

## Default S3 method:
exclude(object, reason, mask, FUN)

Arguments

object	The object to exclude data from.
reason	The reason to add as a reason for exclusion.
mask	A logical vector or numeric index of values to exclude (see details).
FUN	A function to operate on the data (one group at a time) to select reasons for exclusions (see details).

Details

Only one of mask or FUN may be given. If FUN is given, it will be called with two arguments: a data.frame (or similar object) that consists of a single group of the data and the full object (e.g. the PKNCAconc object), FUN(current_group, object), and it must return a logical vector equivalent to mask or a character vector with the reason text given when data should be excluded or NA_character_ when the data should be included (for the current exclusion test).

Value

The object with updated information in the exclude column. The exclude column will contain the reason if mask or FUN indicate. If a previous reason for exclusion was given, then subsequent reasons for exclusion will be added to the first with a semicolon space ("; ") separator.

Methods (by class)

Examples

myconc <- PKNCAconc(data.frame(subject=1,
                               time=0:6,
                               conc=c(1, 2, 3, 2, 1, 0.5, 0.25)),
                    conc~time|subject)
exclude(myconc,
        reason="Carryover",
        mask=c(TRUE, rep(FALSE, 6)))
