我可以通过闪亮的应用程序创建目录/文件吗？

Question

In R, I can use dir.create() function to create a dir or write.csv() function to write a data table. Is it possible to do the same things in a shiny app (instead of use the download button)?

Answer 1

Yes, you can. See:

library(shiny)
ui <- fluidPage(
  h1('my app')
)

server <- function(input, output, session) {
  fdir <- "BBB"
  dir.create(fdir)
}

shinyApp(ui = ui, server = server)
