The GGobi Hack-at-it 2007 was held just before useR! 2007 in Ames Iowa.
The main focus this year was on the data pipeline again, and on pipelines in other software.
Several projects were discussed: the geometric shapes, high-dimensional games, local neighborhood brushing, metabolomics data preprocessing.
The first business meeting of the GGobi Foundation was held, too, working on the by-laws, and other operating procedures.
