GrAPL: a high-level statistical graphics language prototype

Published: 01 June 2000 Publication History

Abstract

The work of statisticians and data analysts requires the fitting of a wide range of statistical models that attempt to explore relationships between variables. Before doing these computations, it is routine to produce exploratory graphs in order to discover these relationships. After model fitting again graphical tools are required in order to explore how satisfactory the model fitting process has been. It is therefore really important for the statistician to be able to produce a wide range of graphs easily and quickly.GrAPL is a prototype language for this purpose; it uses Adrian Smith's RainPro as a graphics engine and attempts to incorporate some of the latest statistical graphical tools that are available in modern statistical packages within a coherent graphical language. APL is used as a `tool of thought' to encourage experimentation within a short development period.
