About the Author
Hrishi V. Mittal has been working with R for a few years in different capacities. He was introduced to the exciting world of data analysis with R when he was working as a Senior Air Quality Scientist at King's College London, where he used R extensively to analyze large amounts of air pollution and traffic data to inform the Mayor of London's Air Quality Strategy. He has experience in various other programming languages, but prefers R for data analysis and visualization. He is actively involved in various R mailing lists, forums and the development of some R packages.
In early 2010, Hrishi started Pretty Graph Limited (www.prettygraph.com), a software company specializing in web-based data visualization products. The company's flagship product, Pretty Graph, uses R as the backend engine for helping researchers and businesses visualize and analyze data. The goal is to bring the power of R to a wider audience by providing a modern graphical user interface which can be accessed by anyone and from anywhere simply by using a web browser.
