Access/use R console when running a shiny app

Question

Does anybody know if one is able to access the R console when running a shiny app? (running the shiny application in background would also be helpful, if that\'s possible)

Answer 1

Can't you use the <<- global assignment operator? I'm not sure how complicated the variable you need to set is, but say you just need to change some variable t to 5.

We could make a textBoxInput that changes the input$new_t variable. Then have an observer:

observeEvent(input$new_t, t <<- input$new_t)

Then, when input$new_t changes, the global variable t changes.

Edit: Another option is to put a browser() in the object that accesses the variable you need to change, right before the variable is accessed.
