R Performs proportion tests to either evaluate the homogeneity of proportions (probabilities of success) in several groups or to test that the proportions are equal to certain given values.

Usage prop. test (x, n, p = NULL, alternative = c ("two. sided", "less", "greater"), conf. level = 0. 95, correct = TRUE)In R, the function used for performing a z-test is prop. test (). Syntax: prop. test (x, n, p = NULL, alternative = c ("two. sided", "less", "greater"), correct = TRUE) Parameters: x = number of successes and failures in data set. n = size of data set. p = probabilities of success. It must be in the range of 0 to 1. Analysis of Prop_test Description Abbreviation: prop Analyze proportions, either of a single proportion against a fixed alternative, a set of proportions evaluated for equality, or a goodness-of-fit test for a single categorical variable or a test of independence for multiple variables.

The two-proportions z-test is used to compare two observed proportions. Description prop. test provides wrapper functions around the function of the same name in stats . These wrappers provide an extended interface (including formulas). prop. test performs an approximate test of a simple null hypothesis about the probability of success in a Bernoulli or multinomial experiment from summarized data or from raw data.
