Abstract:
This presentation introduces SAS users to PROC GREPLAY and the ANNOTATE facility and demonstrates the use of user defined templates to produce a large number of similar graphs (up to 100 or more) on a single page. Of course this would preclude reading valu
es off the axis, but with uniform scaling, these graphs provide very useful visualizations of large data sets. These graphs include scatterplot matrices, but beyond that are great for comparing individual subjects in a study, or any sorts of other grouping
s with a large number of levels (i.e., trellis graphs). They provide quick identification of outliers and influential individuals or groups, allowing for easy data manipulations to check for the robustness of results. The flexibility provided by the ANNOTA
TE facility combined with the power of GREPLAY make these kinds of graphs surprisingly easy to create. Attendees will be provided with a set of templates developed by the speaker.

Derek is a Database Administrator in the Division of Biostatistics at Washington University School of Medicine. His areas of expertise include Base SAS, SAS/FSP, SCL, macro language and SAS/AF. He designs, develops and supports data entry/management system
s for medical research as well as directing and implementing the compilation and documentation of data for several collaborative studies. He also teaches the basics of reading raw data with the SASŪ System in a university-sponsored hands-on seminar several
times a year. He has been using the SAS System to process raw data in many different formats for over 15 years. Derek has won two "Best Speaker" awards at MidWest SAS Users Group conferences and has also received two honorable mentions at SUGI. He is curr
