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’
