When hosting a shiny app (using reticulate) with the new dev RStudio, I have noticed that I cannot terminate the process - I have to restart R. Pressing Esc or clicking the STOP button both do not work.
Minimal example;
library(shiny)
library(reticulate)
ui <- fluidPage(
textOutput("pythonout")
)
server <- function(input, output, session) {
output$pythonout <- renderText({
os <- import("os")
os$getcwd()
})
}
shinyApp(ui, server)
My session info;
> sessionInfo()
