[Unable to load shiny package]

[cho7tom]

Hello,

First of all, thank you very much for the Shiny package, it looks great!

I encounter some difficulties in installing the package, as I cannot install 'websockets' and 'caTools' dependent packages.

Would anyone be able to help me solve this issue?

Please find below my log while trying to install Shiny.

Thank you in advance for your help - I'm quite new to R! -

Please try a different CRAN repository, it sounds like that server might be having some issues. Or just like this:

install.packages("shiny", repos=c("http://rstudio.org/_packages", "http://cran.rstudio.com"))

Many thanks Joe for your answer.

The install was successful. 

However, using the 8100 port doesn't seem to work.. How can I proceed? - it is probably not R- or shiny- related, but you may already have had the question...

> library(shiny)

> runExample("01_hello")

Listening on port 8100

Error in http_response(ws, status = response$status, content_type = response$content_type,  : 

  unused argument(s) (headers = response$headers)

I will mark the post as solved,

Regards,

cho7tom

It looks like you need to upgrade the websockets package to 1.1.6, not sure how that happened.

install.packages('websockets')

I also had this problem using R 2.14.2 and Rstudio (the http response error).

I ended up goign to the CRAN page, downloading the .tar.gz source file for web sockets 1.1.7 and installing for source.

That fixed it...

[Kai Wang]

I encounter a problem when running "01_hello" example too.  When generating a webpage, I got the following error "

Oops! Google Chrome could not connect to localhost:8100", I have been using rstudio and already updated "websockets" package.

Hi Kai,

Are you using the desktop or server (web browser based) version of RStudio?

Hi Joe,

 

I have the same problem ("localhost not found") i am first time user of R studio server, and starting to work on shiny.

[Joe Cheng]

Parth, it won't really work with RStudio Server that way; you need Shiny Server also installed on the server and instead of calling runApp you just let Shiny Server deploy it automatically and you point your browser to a special URL. If you want you can sign up for our beta hosting service which is set up to work in this way, and you will be e-mailed instructions when you're added to the beta.

[Parth khare]

Thanks Joe, i have registered for it and using the same shiny server, i installed shiny package and just gave the commant to run first example as stated in the tutorials, there is where i got the error. I know this sounds a little too dumb question but i couldn't figure out what to do.

Hi,

I got the below error : 

Listening on port 8100

Error in makeTcpServer(host, port, appWrapper$onHeaders, appWrapper$onBodyData,  : 

  '.Random.seed' is not an integer vector but of type 'list'

Could you please help me out with this?

P.S. - I am a newbie in R too and just learning how to use Shiny.

[rtre...@gmail.com]

advice for new (I am one)
sometimes you have to move the directory in the root shiny

[Joe Cheng]

Anant, can you try rm(.Random.seed) and then try again? If that doesn't work, try restarting your R session (if you're in RStudio then it's "Session | Restart R").
