Check your server's request limits. If you are using Apache, you might
want to look at LimitRequestBody and ProxyIOBufferSize.

• By default, Shiny limits file uploads to 5MB per file. You can modify this limit by using the shiny.maxRequestSize option. For example, adding options(shiny.maxRequestSize=30*1024^2) to the top of server.R would increase the limit to 30MB.

The max limit works great. Nice feature. Question: Is there a way to activate the limit when the app is running on a server but not when run locally? I could use interactive() but then the size-limit would also be activated if the app is run locally from a command line.

Hmmm, you could look for both SHINY_PORT and SHINY_SERVER_VERSION environment variables (using Sys.getenv), and if either is set then it means Shiny Server is hosting you.

[Vincent Nijs]

Works great. Thanks Joe!

I put the following in global.R

if(Sys.getenv('SHINY_PORT') == "") options(shiny.maxRequestSize=10000*1024^2)

That way the max limit is 10GB when the app is run locally and 5MB when run from the server.

Are there any workarounds for uploading the data yet? For example, a way to call large amounts of data by streaming the csv file or breaking it up. I am attempting to plot larger data sets but, after hours of research, I really haven't found a solution. Sorry if this is already answered.

Does setting options(shiny.maxRequestSize) to a large value not work?

Hi Joe,

R: 3.2.3

Rstudio: Server edition Version 0.99.893

shiny: 0.13.2

OS: Linux

I am attempting to recreate the app located at http://shiny.rstudio.com/gallery/upload-file.html on my own server but I am getting the error below when I launch from Rstudio server edition(i.e. port 8787).  

Warning: Error in options: unused argument (shiny.maxRequestSize = 100 * 1024^2)
Stack trace (innermost first):
    38: options
     1: runApp
Error in options(shiny.maxRequestSize = 100 * 1024^2) : 
  unused argument (shiny.maxRequestSize = 100 * 1024^2)

Two things to note:

• This error does not occur when I visit the app through chrome (i.e. port 3838).  
• This error does not occur when I try locally (server.R and ui.R on my c drive), launching from the app Rstudio using Rstudio Version 0.99.1249, R 3.3.1 and shiny 0.13.2 

Thanks,

Steve

!?!? The base::options function takes ... parameters, so that error message shouldn't be possible. Unless maybe you're loading a package that masks the "options" function with a different one? Can you print(environment(options)) and see what it says? (I'd expect "<environment: namespace:base>")

Thanks Joe!  I feel a bit sheepish that this issue was caused by two packages sharing a function name but I was thrown off by the fact that it ran fine through port 3838.

Is there a threshold for file uploads to a Shiny app that "should never be exceeded"?

Not particularly. The file is streamed to a temp file as it's uploaded, so it's really a matter of how much max disk space you want to allow one of these uploads to consume.

Good to know... Thanks for the quick response!
