R Packages Used
- For Interactive Application: R Shiny and Shiny Dashboard
Shiny is an R Studio package for developing interactive charts, data visualizations and applications to be hosted on the web using the R programming language. It enables developer to make an interactive application which allow user to understand a certain model or do some data explorations. In this case, we could visualize the underlying rules beyond given datasets which show a clear picture of how those items correlate with each other. Package ‘shiny’Package ‘shinydashboard’
- For Interactive Plot: ggplot2, plotly and gghighlight Package ‘plotly’ Package ‘ggplot2’ Package ‘gghighlight’
- For Choropleth Mapping: tmap, sf and leaflet Package ‘tmap’Package ‘leaflet’
- For HeatMap: heatmaply Package ‘heatmaply’
- For Likert Scale: likert Package ‘likert’
- For Correlation Matrix: corrplot Package ‘corrplot’
- For data preparation: sqldf(for SQL operations in R),dplyr,stringr Package ‘sqldf’ Package ‘dplyr’ Package ‘stringr’
