GIS IN R• Analyze spatial data without QGIS or ArcGIS
• Simplest data
• Provide Many GIS Packages
• Applied Spatial Data Analysis with R (Roger S. Bivand, Edzer Pebesma and V. Gómez-Rubio/ UseR! Series, Springer 2nd ed. 2013)
SHINY IN R> install.packages(shiny) > library(shiny) > runApp()
- Interactive - Reactive UI - Base on Twitter - Bootstrap - HTML, CSS, javascript & jQuery
GIS PACKAGES
