How it happens : R-shiny: “shiny” , “shinydashboard” and “shinyjs” are powerful packages and that enables us to develop web based interactive visualization.
#ui.R : UI component ( header, body, sidebar)
header <- dashboardHeader( …)
body <- dashboardBody( … )
side <- dashboardSidebar(…)
dashboardPage(header, body, side)
# all backend activities
Once you click “Run App” on Rstudio, application/API is ready and then you can republish it on shiny server ( once you have signed up) to make it online..
