apa: apa

In yarrr: A Companion to the e-Book "YaRrr!: The Pirate's Guide to R"

Description

This function takes a hypothesis test object (e.g.; t.test(), cor.test(), chisq.test()) as an input, and returns a string with the test result in APA format.

Usage

apa(test.object, tails = 2, sig.digits = 2, p.lb = 0.01)

Arguments

test.object	A hypothesis test object generated by functions such as t.test(), cor.test, chisq.test()
tails	The number of tails in the test (1 or 2)
sig.digits	The number of digits results are rounded to
p.lb	The lower bound of the p-value display. If the p-value is less than p.lb, the exact value will not be displayed.

Examples

x <- rnorm(100)
y <- x + rnorm(100)
a <- sample(1:3, size = 200, prob = c(.3, .2, .5), replace = TRUE)
b <- sample(1:3, size = 200, prob = c(.3, .2, .5), replace = TRUE)

apa(t.test(x, y))
apa(cor.test(x, y))
apa(chisq.test(table(a, b)))
