Data Analysis and Visualization
with Excel, R  and Google Tools
Analysis, Chart and  Map Tools to Better Understand  Our Data

Note To Readers:  The time has come for me to shut down this site, a task I dread. When I started this site in February, 2006 I had a vague idea about what I wanted to do, show readers how to make more effective charts with Excel. That mission has morphed to include Google Map tools, global warming data analysis, time series analysis and R.

My data analysis focus  has changed from Excel to R. I have switched from FrontPage to WordPress. I now have a Climate Change blog here and a local blog here
