Data Menu Commands

Load

This enables you to load data directly into GenStat from a variety of sources, as follows:

ASCII files where data are specified in columns
Resume files where data has been saved previously using the Save command.
Data files - GenStat spreadsheet (.gsh), other spreadsheet and data formats.
From Clipboard where data are in column format on the clipboard.
ODBC Data and Retrieval files

Save

This allows you to save the current GenStat data to a binary file (.gsv). You can load data in this format back into GenStat using the Resume option of Load. Note that the data are saved using a RECORD statement.

Clear all Data

This deletes all current data structures from GenStat, by issuing an ENDJOB command. Data in open spreadsheet windows can be restored to GenStat using the Update section from the Spread menu.

Calculations

Calculates new data using any general expression.

Transformations

Transforms a data variate according to a transformation chosen from a list of common transformations.

Unit conversions

Performs standard unit conversions for different types of measurements.

Matrix Calculations

Performs matrix calculations using a subset of functions from the general Calculations menu.

Set Calculations

Performs Boolean arithmetic on sets contained within variates.

Probability Calculations

Performs probability calculations for a range of discrete and continuous distributions.

Generate Random Sample

Generates a random sample from a chosen distribution.

Random Permutations

This performs a random permutation of the units for a set of factors and/or variates.

Ranks

Calculates the ranks of values within a sample.

Form Groups (Factors)

Converts data from a variate or text into a factor.

Form Multiple-response factors

Produces multiple-response factors from a set of variates or text structures coding individual responses.

Form Similarity Matrix

Forms a symmetric matrix containing similarities between each pair of observations based on data contained in a set of variates.

Append

Appends a set of vectors of the same type (factor, text, or variate) into a single vector of the same type.

Subset

Forms a new vector containing a subset of the values of an existing one.

Display

The data display window provides a display of all the data structures that are currently available within GenStat. The view contains a tree list of different types of data folders where each folder list the data structures for that data type. You can also use this view to display the contents of a data structure into the Output Window and delete unwanted data structures. If the Use docked data view option on the General tab of the Options is selected then the data will be displayed in a docked view on the left hand side of the interafce. If this option is not selected then the data will be displayed in a dialog.
