format_normalize: Normalizes a variable to specified experimental period

In VegardLysne/bssg: Functions Used At BSSG

Normalizes a variable to specified experimental period

Description

Subtracting mean of the specified period from every value in the variable that's being transformed, i.e. mean of the baseline period

Usage

format_normalize(.data, ID_var, variable, phase_var = Experiment_period,
  phase_value = Baseline, add = 0)

Arguments

.data	a tibble
ID_var	the ID variable, for grouping
variable	name of the variable that is going to be transformed
phase_var	name of the variable containing experimental phases, defaults to Experiment_period
phase_value	name of the value of phase_var which you normalizes towards, defaults to Baseline
add	Optional argument, a number to add to every value if you want the mean to be something other than 0. Defaults to 0.

Value

a tibble, where one variable is transformed

Examples

Normalizing variable bodytemperature to the Baseline period,
contained in variable Experiment_period in data set d

d %>%
  format_normalize(variable = bodytemperature,
                   ID_var = Id,
                   phase_var = Experiment_period,
                   phase_value = Baseline,
                   add = 0)
