psr {rankFD}

A function for computing pseudo-ranks of data

Description

The psr() function calculates pseuo-ranks of data in general factorial designs. It returns the input data set complemented by an additional variable containing the pseudo-ranks. We note that more efficient algorithms for the computation of pseudo-ranks are implemented within the package pseudorank.

Usage

psr(formula, data, psranks = "pseudorank")

Arguments

formula

A model formula object. The left hand side contains the response variable and the right hand side contains the factor variables of interest. Please use one-way layouts for the computation of the pseudo-ranks only. In case of higher-way layouts, please use a 'help factor' that#' shrinks the layout to a one-way design.

data

A data.frame, list or environment containing the variables in

formula. The default option is NULL.

psranks

A header specifying the name of the pseudo ranks in the output data set.

Details

The pseudo-ranks are exported within a new column attached to the given data set.
