Hi there thanks for the answer. >> But are their better ways / best practices? >You'll have to ask questions like these on a Shiny forum. Done.

Dear R addicts, Back in 2006, I posted the proposition for a tweak of the Sweave driver so that PNG figures can be produced instead of eps/pdf : https://stat.ethz.ch/pipermail/r-help/2006-March/102122.html The amount of code modified is tiny (it was designed to induce minimal changes to the official code), but so far the driver seems to have been useful to a number of users. From 2006 on,

Dear all, It is my understanding that using 'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj'

Dear R developers, I am having a slightly weird issue with a S4 method defined in my package adegenet 1.2-4, with R 2.11.0. As far as I know, the problem is new, and the code implementing the method has not changed for more than a year and worked well so far. The problem is the following. I define, in the package, a method "[" for the S4 class 'genind'. The method's

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, ...) {

Thank you Thierry. I'm trying to following your suggestion in the example below, but getting: Error in get("xs", envir = my.env) : object 'my.env' not found. library(shiny) library(shinydashboard) myApp <- function(x, ...) { xs <- scale(x) my.env <- new.env() assign("xs", xs, envir = my.env) shiny::runApp(app) } app = shinyApp( ui =

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.

Dear List, I have a wrapper function that creates a Shiny App, as illustrated below. I'd like to include the function myApp() inside a package. I'd appreciate your guidance here, as I could not find good instructions on this online. myApp <- function(x) { require(shiny) shinyApp( ui = fluidPage( sidebarLayout( sidebarPanel(sliderInput("n",

Hola Miguel-Ángel esa instrucción la he puesto para que no me haga el break y se reinicie RStudio. 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.

De acuerdo Carlos pero en mi ordenador no funciona y me da el error que he comentado. Muchas gracias por tu colaboración. Saludos, Juan El 04/03/2018 a las 20:09, Carlos J.

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

I would like to select polygons from an existing spatial polygon data set interactively in a shiny leaflet map. The process is straightforward in leaflet/ mapedit, however I need to include the procedure in a shiny app map interface. 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:

Muchas gracias Miguel-Ángel he probado la opción de la consola de R y sigue el problema, en este caso intenta mostrar en la pantalla del navegador la salida del programa pero se cierra R, supongo por tanto que se aborta el proceso.

Hello, Here is a late answer, but an answer nonetheless to the question I asked almost one year ago on this list: > On Wed, 29 Mar 2006, Thibaut Jombart wrote: >> Hello list, <http://tolstoy.newcastle.edu.au/R/help/06/03/24318.html#24322qlink1> />> / />> does anyone know if Monmonier algorithm is available in R?

Hello list, does anyone know if Monmonier algorithm is available in R? I've checked several spatial libraries, but I didn't find anything related to it. However, there is a huge documentation and I may have missed it. Before coding it, I'd like to be sure it doesn't already exist.

Hello list, despite I already posted a mail on this topic on R help, I guess this place may be more appropriate. I'll make it shorter this time. Sorry for posting twice. I found that using pixmap pictures in a Sweave document was sometimes almost impossible, due to the huge size of the pdf pictures produced. The first solution I found was to save pictures in png, when too heavy in pdf.

Hello there, I have been used shiny package on Windows without any problem. Recently I switched to Linux OS(Ubuntu 12.04), and installed the latest R version 3.0.1. But I couldn't install "shiny" for some reasons. Here are the error message: ** preparing package for lazy loading Error : package ‘codetools’ was built before R 3.0.0: please re-install it Error : unable to load R

Estoy trabajando generando mapas a partir de un conjunto de datos. No puedo encontrar la forma de manipular el tamaño de los mapas. He buscado en páginas de Shiny y no pude encontrar una solución ¿Alguien me puede orientar? No he puesto una imagen para no recargar el servidor de correo.
