"Managing Many Models"
Visualization alone is not enough to solve most data analysis challenges. The data may be too big or too messy to show in a single plot. In this talk, Wickham will outline his current thinking about how the synthesis of visualization, modeling, and data manipulation allows for effective exploration and understanding of large and complex datasets. This work is embedded in R, so Wickham will not only talk about the ideas but also show concrete code for working with large sets of models. He'll demonstrate how to combine the dplyr and purrr packages to fit many models, then use tidyr and broom to convert to tidy data which can be visualized with ggplot2.
Hadley Wickham is chief scientist at RStudio, which provides the most widely used open source and enterprise-ready professional software for the R statistical computing environment. He is an adjunct professor of statistics at the University of Auckland and an adjunct assistant professor of statistics at Rice University. Wickham works to build tools (computational and cognitive) that make data science easier, faster, and more fun.
