Hello, I'm relatively new to using R and shiny. Currently, I'm getting the Error: Conflict (HTTP 409) when trying to access an html file from dropbox and this is fine, I know the reason. What I do have a problem with is trying to find a way to change Error code message. Instead of simply "Error: Conflict (HTTP 409)", I would a message a client might be able to understand.

Hi All, I am not sure if this is a relevant platform to ask but I have tried other more related platforms and haven't had any luck so i thought i would try my luck here. Basically I want to generate a selectInput widget with a conditional under renderUI in Shiny. The number of widgets generated will depend on the number of variables a user selects.

Hola, Shiny utiliza la función selectInput en ui.R (donde se declaran los métodos y las etiquetas que se muestran en pantalla) y la variable input$nombre_usado_en_ui para tomar el valor elegido en el server.R Puedes consultar el tutorial de shiny en: http://rstudio.github.io/shiny/tutorial/#shiny-text Por ejemplo (copiado de ahí) en ui.R sidebarPanel( selectInput("dataset",

Thanks Eric for your pointer. However I just altered the argument of load() function a little bit to get that loaded.

Hi Christofer, The shiny code you have written does not depend on loading the Dat.RData file. I commented out that line and ran your shiny app on my machine and it works fine. What happens if you comment out (or remove) the line load("/home/ubuntu/Dat.RData) Does your shiny app still fail? If so, then your problem is quite basic with your AWS setup. Try to work through a simple

Hi Eric, thanks for your further pointer. I have put a line with load() function just as an illustration of a bigger project of mine, which appears failing due to load() function issue.

Hi Christofer, The directory /srv/shiny-server would normally be owned by the root user. Your options would seem to be to either (1) bring up the R session as root (dangerous) or (2) try copying the file to your local directory and read it from there (if allowed). e.g. from the Unix shell: > cd ~ (i.e. cd to your home directory) > cp /srv/shiny-server/Dat.Rdata . (Note the '.' at

Hi again, I hope this is the right place to post my question on running R within Ubuntu, however if not, any pointer on right distribution list will be helpful. I am currently using R in Ubuntu which is hosted in Amazon - AWS. I have a .Rdata file in AWS which I am trying to load in R. Used following code, however, fails to load showing some permission issue. However that same .Rdata file is
