ZTrans

A (non-empty) matrix with data values. Columns should be different traits and rows unique observations of those traits

DATA

This function converts the columns in a data matrix into z-scores. The score is computed by subracting each observation in a column from the column mean and divding by the column standard deviation. Each column is converted independently of the others missing values are ignored in the calculation.

Code to support a systems biology research program from inception through publication.  The methods focus on dimension reduction approaches to detect patterns in complex, multivariate experimental data and places an emphasis on informative visualizations.  The goal for this project is to create a package that will evolve over time, thereby remaining relevant and reflective of current methods and techniques.  As a result, we encourage suggested additions to the package, both methodological and graphical.
