Github repo with some example code: https://github.com/karthik/shiny The most up to date resource on Shiny: http://shiny.rstudio.com/ Also see some amazing cheatsheets here: http://www.rstudio.com/resources/cheatsheets/
- server.R holds the behind the scenes info
- ui.R holds the interface
Best way to learn: Try building an app. Best resource: cheatsheets rstudio.com/resources/cheatsheets
## ui.R
shinyUI( fluidPage(
titlePanel("This is a shiny app"),
sidebarLayout(
sidebarPanel(
selectInput("x", "x variable", names(iris))
selectInput("y", "y variable", names(iris), names(iris)[[2]])
),
mainPanel()
)
))
## server.R
## any code that runs once on each server
## put that code *before* the shinyServer() call
library(ggplot2)
shinyServer(function(input, output){
output$gg <-
})
