TIBCO Spotfire® Statistics Services Users Guide

Transient and persistent data

For all but the simplest calculations, you must read data from input data files and write results to output data files and graphics files.

Often, it is useful to take an output data file from one calculation and use it as an input to another.Spotfire Statistics Services supports this practice by maintaining "transient" file directories for storing output data files, and "persistent" file directories that can be used for both input and output files.

Note: Additionally, Spotfire Statistics Services provides the class SplusDataRequest, a collection of R objects and/or an encapsulated data set, which is passed as an argument to an eval() function. See Pass in a data object for more information about using this object.
