tgt_bp: Creates a set of logical variables which compare blood...

In KHP-IDEO/rIDEO: IDEO functions

Description

The function takes an existing dataframe, which contains variables of both systolic and diastolic observations, and measures these against a set of treatment target levels. The target levels are set as: 130/80, 140/80, 140/90 and 150/90. A separate logical variable is produced for each target, with a TRUE or FALSE value to indicate whether the test value is below the respective target levels. The full set of target variables are appended to the existing dataframe.

Usage

tgt_bp(x)

Arguments

x	Dataframe containing a set of blood pressure observations. The created target variables will be appended to this dataframe.
y	Numeric vector of systolic blood pressure values.
z	Numeric vector of diastolic blood pressure values.

Examples

# systolic bp values
sys <- sample(90:200, 50)

# diastolic bp values
dias <- sample(40:120, 50)

# combine into dataframe [bp pairs may be unrealistic due to randomness]
bp <- tibble::tibble(sys, dias)

# Measure the blood pressure values against the full set of targets, adding logical variables to the dataframe
data <- tgt_bp(bp, sys, dias)
