ReadSortFile: Read a file of free sorting data

In FreeSortR: Free Sorting Data Analysis

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

filename	File name (and address if necessary)
terms	Boolean indicating if groups are coded by terms (terms=TRUE) or numbers (default terms=FALSE)
septerms	Symbol for separating terms (default is septerms=",") if terms=TRUE
sep	Symbol for separating data in the csv file (default is sep=";")
dec	Decimal separator (default is dec=".")

Value

List of the following components :

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

Examples

  # dat<-ReadSortFile ("FSdata.csv")
  # Sort<-SortingPartition(dat$MatSort)
