+     "Multivariate data analysis is the simultaneous observation of more than 
one
+characteristic.  In contrast to the analysis of univariate data, in this 
approach
+not only a single variable or the relation between two variables can be 
investigated,
+but the relations between many attributes can be considered.  For the 
statistical
+analysis of chemical data one has to take into account the special structure of
+this type of data.  This package contains about 30 functions, mostly for 
regression,
+classification and model evaluation and includes some data sets used in the R 
help
+examples.  It was designed as a R companion to the book \"Introduction to 
Multivariate
+Statistical Analysis in Chemometrics\" written by K. Varmuza and P. Filzmoser 
(2009).")
