    We can see screenshot error image on the link in your post, we need your code and maybe data to reproduce the same error. – zx8754 Jun 22 '16 at 08:54
  • `library(shiny) library(leaflet) library(dplyr) shinyServer(function(input, output) { output$values <- renderLeaflet({ inFile <- input$file1 if (is.null(inFile)) return(NULL) dat <- read.csv(inFile$datapath, header=input$header, sep=input$sep, quote=input$quote) p <- leaflet() %>% addTiles() %>% addCircles(lng=dat$longitude, lat=dat$latitude , popup = dat$member_id) }) })` – xiukun Jun 22 '16 at 09:18

It seems there is no dplyr package installed in the library used by the R process which your shiny server is using.

from browser console:

Listening on http://127.0.0.1:56037
Warning: Error in library: there is no package called ‘dplyr’
Stack trace (innermost first):
    38: library
     1: runApp
Error in library(dplyr) : there is no package called ‘dplyr’

Ensure that you have the package installed in the library folder used by shiny server. E.g. in my case I have separate R used by RStudio so that development is separated from live app.

My library sits in usr//lib64//R//library therefore in linux i will run R as superuser sudo R and then install.packages("dplyr", lib="usr//lib64//R//library//")

  • I have installed dplyr package,but it doesn't work still. – xiukun Jun 23 '16 at 05:01
  • The error is definitely due to missing library, i have tested on my server and adding something like `library(aareshape2)` will return same error and cause the app to fail. Which OS are you using on your server? My best guess is we need to check for installed packages, which library path they are installed in and if the user running the shiny app has permissions to read given folder/files – PeterS Jun 23 '16 at 08:43
  • haha, it is diffcult to me. I don't know if shiny App has permissions. it is first time to run APP in ubutun shinyserver(I can run shiny default example).do you have good idea?(my package lib is "/usr/local/lib/R/site-library","/usr/lib/R/site-library","/usr/lib/R/library") – xiukun Jun 24 '16 at 02:07
