Feed: R-bloggers. Author: Euthymios Kasvikis. INTRODUCTION The ggvis package is used to make interactive data visualizations. The fact that it combines shiny’s reactive programming model and dplyr’s grammar of data transformation make it a useful tool for data scientists. This package may allows us to implement features like interactivity, but on the other hand every interactive ggvis plot must be connected to a running R session.Before proceeding, please follow our short tutorial.Look at the examples given and try to understand the logic behind them. Then try to solve the exercises below using R and without looking at the answers. Then ... Read More
