sim.chisq.test.ind

Description

sim.chisq.test.ind

Usage

sim.chisq.test.ind(
  simdat.chisq.ind,
  correct = TRUE,
  experiment.name = "experiment",
  group.name = "variable",
  value.name = "value"
)

Arguments

simdat.chisq.ind

Data for use in chi squared tests of independence across one or more experiments. Structure is in the form returned by the function simitation::sim.chisq.ind().

correct

See help(chisq.test).

experiment.name

A character value providing the name of the column identifying the experiment.

group.name

A character value providing the name of the column of the group labels.

value.name

A character value providing the name of the column identifying the values.

Value

A data frame with results of the chi-squared tests for each experiment.
