similar to: Shiny App inside R Package

Dear List, I'm trying to add a function that calls a Shiny App in my R package. The issue is that within my function, I'm creating objects that I'd like to pass to the app. For instance, from the example below, I'm getting "Error: object 'xs' not found". How can I pass "xs" explicitly to shinyApp()? *Under R directory:* myApp <- function(x, ...) {

Dear Axel, I've used environment for such problems. assign("xs", xs, envir = my.env) in the myApp function get("xs", envir = my.env) in the server function Best regards, ir.

Hi All: This is really getting into the weeds, but I am hoping someone will have a solution. I am trying to use dygrahs for R, within Shiny. The situation arises when I am combining a number of dygraphs into one plot. If I am just in an RNotebook, if you look at: https://stackoverflow.com/questions/30509866/for-loop-over-dygraph-does-not-work-in-r the solution to have the plot shown from a

Hello everybody, I have experience coding with R, but am brand new to R Shiny. I am trying to produce an application that will allow users to upload their own dataset, select columns they want an ANOVA analysis run on, and generate graphs that will allow users to view their results.

I cannot work out how to incorporate the selectMap() in the shiny app. An error is returned: Here is some toy code showing the code in using leaflet locally:

Si quito esa instrucción y hago que se pase la salida al wiewer panel de Rstudio me aparece el mismo error pero además se aborta la sesión de RStudio y con la instrucción lo que cambia es que no aborta la sesión.

Muchas gracias Miguel-Ángel por tus explicaciones, pero empezando por el final digo reinicia pero en realidad es que se aborta el proceso. Independiente de la instrucción print la cuestión es que el programa en mi ordenador aborta siempre de forma independiente que lo haga en wiewer externa, interna o "medio-pensionista". Sin embargo en otro ordenador que tengo con windows 10 y R de 32
