Description

multiculturalSortingSpices. An excel file storing the data from a sorting task: 62 participants from 5 different countries (USA, France, India, Spain, and Vietnam) sorted 16 different spices (including 6 mixtures of spices). This excel file can be accessed with the R-command system.file(), and can be read by the function DistatisR::read.df.excel (note that the package DistatisR needs to have been installed first from Github as devtools::install_github('HerveAbdi/DistatisR')).

Details

The data are stored in an excel file containing 3 sheets. The first sheet, called DataSort contains the sorting data: the rows are the products and the columns are the assessors. The data are organized and coded as indicated in the help for distatis (see also the Abdi et al.s' 2007 Distatis paper). Some spices are mixtures of several spices and the names are short names to make the graphs easier to read (the long names are given in the sheet legend4Spices). The first letter of the name of the assessors gives their nationalities: S for Spanish (10), V for Vietnamese (6), I for Indian (15), F for French (21), and A for American (9).
