summarize_simulations: Summarize simulated numeric variables

In simulab: Simulates a Wide Variety of Data Shapes, Sizes and Distributions

Summarize simulated numeric variables

Description

Summarize simulated numeric variables

Usage

summarize_simulations(data, by = NULL, variables = NULL)

Arguments

data	Simulation data: a simulab_sim or a plain base data.frame.
by	Optional character vector of grouping column names. NULL, the default, summarizes all rows together.
variables	Character vector of numeric variables to summarize. NULL, the default, selects every numeric non-grouping column.

Value

A plain base data.frame with one row per group and variable: the by columns (none when by is NULL), then variable, observations (the non-missing count), mean, sd, minimum and maximum. Missing values are left out of the statistics; a group with none left reports NA statistics.

Examples

data <- simulate_ttest(n_a = 50, n_b = 50, mean_a = 0, mean_b = 0.6, seed = 1)
summarize_simulations(data, by = "group", variables = "outcome")
