Is it possible to run a python script in R shiny

Question

I have some data sets that are in a weird format and have written some python scripts to convert to csv format to use in R. Is it possible to call the python scripts in an R shiny app?

Answer 1

I know the topic is close but now you can make shinyApp with python using reticulate.

This is a minimalist example.

library(reticulate)
library(shiny)

ui <- fluidPage(
  plotOutput(outputId = "plot01")
)

server <- function(input, output){

  # Import module
  plt <- import("matplotlib.pyplot")

  output$plot01 <- renderPlot({
    plt$plot(1:10)
    plt$show()
  })
}

shinyApp(ui, server)

Answer 2

Here is a minimal Shiny app that makes use of rPython to execute python calls.

library(shiny)
library(rPython)

ui = bootstrapPage(
  sliderInput('x', 'Set x', 0, 10, 5),
  verbatimTextOutput('out1')
)

server = function(input, output, session){
  output$out1 <- renderPrint({
    python.call("len", 1:input$x)
  })
}

runApp(list(ui = ui, server = server))
