iqr_glu {iglu}

Calculate glucose level iqr

Description

The function iqr_glu outputs the distance between the 25th percentile and the 25th percentile of the glucose values in a tibble object.

Usage

iqr_glu(data)

Arguments

data

DataFrame object with column names "id", "time", and "gl", or numeric vector of glucose values.

Details

A tibble object with 1 row for each subject, a column for subject id and a column for the IQR values is returned. NA glucose values are omitted from the calculation of the IQR.

Value

If a data.frame object is passed, then a tibble object with two columns: subject id and corresponding IQR value is returned. If a vector of glucose values is passed, then a tibble object with just the IQR value is returned. as.numeric() can be wrapped around the latter to output just a numeric value.

Examples

data(example_data_1_subject)
iqr_glu(example_data_1_subject)

data(example_data_5_subject)
iqr_glu(example_data_5_subject)
