RStudio Shiny ERROR: there is no package called "shinydashboard"

Question

I am trying to get http://rstudio.github.io/shinydashboard/ working on my Ubuntu 14.10 laptop.

I followed the installation instructions here:

http://rstudio.github.io/shinydashboard/get_started.html

Basic shiny pages work. For example:

http://localhost:3838/sample-apps/hello/

But when I try one of the shinydashboard examples, I get the error:

http://localhost:3838/sample-apps/shiny/

ERROR: there is no package called "shinydashboard"

If I run an R session in a terminal, I can load the shinydashboard library, and I get a browser window with the dashboard if I copy+paste this code in the R session:

library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody()
)

server <- function(input, output) { }

shinyApp(ui, server)

It says:

Attaching package: 'shinydashboard'

The following object is masked from 'package:graphics':

    box

> 
> ui <- dashboardPage(
+   dashboardHeader(),
+   dashboardSidebar(),
+   dashboardBody()
+ )
> 
> server <- function(input, output) { }
> 
> shinyApp(ui, server)

Listening on http://127.0.0.1:7093

I tried to install the devel version of the shiny server, but that also didn't help. Here is my sessionInfo():

EDITED:

More info:

ls -ld /usr/local/lib/R/site-library
drwxrwsr-x 11 root staff 4096 Mar  1 12:47 /usr/local/lib/R/site-library

Any ideas why I is it not working on http://localhost:3838 ? Which packaged need installing as root ?

You don't have `shinydashboard` installed. – kristang Mar 01 '15 at 15:49 — kristang, Mar 01 '15 at 15:49

The problem is that shiny-server cannot find the packages that you install because it runs them as a different user which is called shiny. This user is created upon installation of shiny-server

The easiest (and safest IMHO) way to solve this is to just install the packages as the shiny user, using the following steps.

Set a password for the user using sudo passwd shiny, now enter and confirm a password
Switch to the shiny account using: su - shiny
Call up R using $ R (without sudo)
Install the required packages, in this case: install.packages("shinydashboard")

Note that if you have rstudio-server installed on the same machine then you can perform steps 2-4 using that interface. Simply go the same domain/ip and use :8787 for the rstudio-server interface instead of :3838 for shiny-server.

Thank-you. Very helpful answer. – ixodid Jul 26 '18 at 00:51 — ixodid, Jul 26 '18 at 00:51

On Ubuntu (and Debian) you have several choices.

Do ls -ld /usr/local/lib/R/site-library and note that the directory is owned by group adm. Make yourself part of that group, or alternatively change the group to one you are a member of. Now you can just write to that directory, so a plain old install.packages() will work.
Use littler via sudo apt-get install littler and its handy script(s) install.r and install2.r. I use these a lot from the command-line on numerous machines at work and home. Then this is as simple as install.r shinydashboard (once you copied or linked install.r somewhere into your $PATH).
If you insist, use a sledgehammer and start R as root. That is generally not a good idea due to permissions escalation.

Cool, I will try that. How do I "make myself part of the group". Excuse my naivete... – 719016 Mar 03 '15 at 15:34
The are a number of ways. Via the Settings GUI in Ubuntu, via the `adduser` command, ... Maybe see here on [askubuntu](http://askubuntu.com/search?q=add+user+to+group) where this simple query gave 1300+ results. – Dirk Eddelbuettel Mar 03 '15 at 15:36
Trying this now: `sudo gpasswd -a ${USER} staff` – 719016 Mar 03 '15 at 16:27
@DirkEddelbuettel would this first option work on Fedora? – Bastiaan Quast Oct 07 '15 at 13:16
"Possibly" but some things hinge on details (eg value of what `.libPaths()` returns for you) so you better ask on the r-sig-fedora list. – Dirk Eddelbuettel Oct 07 '15 at 13:54

If you use Shiny Server, all your R packages need to be installed with root privilege. See Section 1.3.4 of the Shiny Server admin guide for more details.

That's pretty bad advice as it opens `sudo` to anything triggered from a semi-randomly pulled-in package. Instead, run as a user who is part of the group owning the directory. On Debian/Ubuntu this works out of the box and does not require `sudo` -- only local admin cooperation to make you part of that group. – Dirk Eddelbuettel Mar 03 '15 at 14:45

This answer should work: https://stackoverflow.com/a/28834778/719016

I now realised it was a permissions issue when installing packages as R instead of sudo R.

I momentarily resolved it by installing as $USER and then pointing to the library with lib.loc:

library(shinydashboard, lib.loc="/home/avilella/R/x86_64-pc-linux-gnu-library/3.1")

I personally do not like directories below `$HOME` as other users cannot see them. – Dirk Eddelbuettel Mar 03 '15 at 16:56

I have the similar problem for "d3heatmap" package. It runs in RStudio (desktop and web) but gets an error in the web browser.

The only one workable solution was to install package from R command line under "root" account.
