median_glu: Calculate median glucose level

Description

The function median_glu is a wrapper for the base function median(). Output is a tibble object with subject id and median values.

Usage

median_glu(data)

Value

If a data.frame object is passed, then a tibble object with two columns: subject id and corresponding median value is returned. If a vector of glucose values is passed, then a tibble object with just the median 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 median values is returned. NA glucose values are omitted from the calculation of the median.
