range_glu: Calculate glucose level range

Description

The function range_glu outputs the distance between minimum and maximum glucose values per subject in a tibble object.

Usage

range_glu(data)

Value

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

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 range values is returned. NA glucose values are omitted from the calculation of the range.

Examples

data(example_data_1_subject)
range_glu(example_data_1_subject)

data(example_data_5_subject)
range_glu(example_data_5_subject)
