day_min_sd: Calculates the (person level) standard deviation of daily...

In seanchrismurphy/emacalc:

Description

This is a function that returns a dataframe in which the person-level standard deviation of the daily minimums of any input variables has been calculated. Output variables will be named 'input_variable_day_min_sd'. Note carefully that this is -not- the min of the standard deviations within each day. Rather, the minimum at each day is taken, then the standard deviation of these minima is calculated.

Usage

day_min_sd(data, variables, person_id, day_id)

Arguments

data	The input dataset
variables	A character vector of input variables e.g. c('negemo', 'posemo').
person_id	The person level grouping variable - this should be your person id variable.
day_id	The day level grouping variable - this should be your day id variable.
