Chapter 15 Conclusion and Next Steps

Congratulations, you’ve reached the end of this book!

We hope we have motivated you to continue your amazing journey into the emerging computational sensory science field. To give you a little hand, we are listing here list some other resources we would recommend and a summary of the main useful packages for sensory and consumer data analysis/visualization, including the ones we used throughout this book.

15.2 Useful R Packages

  • FactoMineR: package dedicated to multivariate Exploratory Data Analysis including Principal Components Analysis (PCA), Correspondence analysis (CA), Multiple Correspondence Analysis (MCA), clustering.

  • FactoExtra: package that makes easy to extract and visualize the output of exploratory multivariate data analyses, including Principal Component Analysis (PCA), Correspondence Analysis (CA), Multiple Correspondence Analysis (MCA), Multiple Factor Analysis (MFA), Hierarchical Clustering (HCKUST) and partioning Clustering (E.g. k-means, PAM,CLARA, etc.)

  • SensR: package for Thurstonian Models for sensory discrimination methods, including duotrio, tetrad, triangle, 2-AFC, 3-AFC, A-not A, same-different, 2-AC and degree-of-difference. This package enables the calculation of d-primes, standard errors of d-primes, sample size and power computations, and comparisons of different d-primes.

  • SensoMineR: package dedicated to the statistical analysis of sensory data. It tackles the characterization of the products, panel performance assessment, links between sensory and instrumental data, consumer’s preferences, napping evaluation, optimal designs.

  • tempR: package for Analysis and visualization of data from temporal sensory methods, including temporal check-all-that-apply (TCATA) and temporal dominance of sensation.

  • sensmixed: package to analyze sensory and consumer data within mixed effects model framework.

  • corrplot: package that provides a visual exploratory tool on correlation matrix that supports automatic variable reordering to help detect hidden patterns among variables.

  • stats: this This package contains functions for statistical calculations and random number generation. The analysis include ANOVA, posthoc tests, Clustering, Correlation, multivariate analysis, among many others.
