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. However, I am getting the following error: *"Argument is of length zero."* Being new to Shiny, I am

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. Below is the line what I tried. ubuntu at ip-172-31-23-148:~$ R R version 3.4.2 (2017-09-28) -- "Short Summer" Copyright (C) 2017 The R Foundation for Statistical Computing Platform: x86_64-pc-linux-gnu (64-bit) R is free software and comes with ABSOLUTELY NO

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. If I comment out that line my shiny app is working correctly locally and globally. otherwise, locally my shiny app is working but not with AWS.

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
