check_normality: check_normality

In gladstone-institutes/calcPower: Power Calculation for biological experiments

check_normality

Description

This function makes a quantile-quantile (qq) plot of the residual values of the mixed effects model. Users can check the normality of residual values by examining qqplot.

Usage

check_normality(
  data,
  condition_column,
  experimental_columns,
  response_column,
  condition_is_categorical,
  repeatable_columns = NA,
  response_is_categorical = FALSE,
  image_title = NULL
)

Arguments

data	Input data
condition_column	Name of the condition variable (ex variable with values such as control/case). The input file has to have a corresponding column name
experimental_columns	Name of the variable related to experimental design such as "experiment", "plate", and "cell_line".
response_column	Name of the variable observed by performing the experiment. ex) intensity.
condition_is_categorical	Specify whether the condition variable is categorical. TRUE: Categorical, FALSE: Continuous.
repeatable_columns	Name of experimental variables that may appear repeatedly with the same ID. For example, cell_line C1 may appear in multiple experiments, but plate P1 cannot appear in more than one experiment
response_is_categorical	Default: the observed variable is continuous Categorical response variable will be implemented in the future. TRUE: Categorical , FALSE: Continuous (default).
image_title	title of the qq plot

Value

A quantile-quantile (qq) plot of residual values in a mixed-effects model

Examples

check_normality(data,"classif",c("experiment","line"),"feature1","TRUE")
