ReadSortFile {FreeSortR}

Read a file of free sorting data

Description

The function (ReadSortFile()) reads a csv file of free sorting data.

The file contains stimuli as rows and subjects as columns. For a subject, two stimuli in the same group are coded by the same symbol. First row contains the labels of subjects and first column contains the labels of stimuli.

For each subject, the coding of a group may be a number or a list of terms describing the group (terms have to be separated by a symbol, as a comma).

Returns a matrix of sorting and, if this is adequate, matrices describing the use of terms by subjects.

Usage

ReadSortFile(filename, terms=FALSE, septerms=",", sep=";", dec=".")

Arguments

terms

Boolean indicating if groups are coded by terms (terms=TRUE) or numbers (default terms=FALSE)

septerms

sep

Symbol for separating data in the csv file (default is sep=";")

dec

Value

MatSort

Matrix of sorting groups (may be used by the function SortingPartition)

MatTerms

Matrix of occurences of the terms used by the subjects

Stress

List of terms used by each subject
