Check your server'southward request limits. If you lot are using Apache, y'all might
desire to look at LimitRequestBody and ProxyIOBufferSize.

• By default, Shiny limits file uploads to 5MB per file. You can modify this limit by using theshiny.maxRequestSize option. For instance, addingoptions(shiny.maxRequestSize=30*1024^2) to the acme ofserver.R would increment the limit to 30MB.

The max limit works great. Dainty 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() just then the size-limit would also be activated if the app is run locally from a command line.

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

Works bang-up. Thanks Joe!

I put the following in global.R

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

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

Are there whatever workarounds for uploading the data yet? For example, a way to phone call large amounts of data past streaming the csv file or breaking information technology up. I am attempting to plot larger information sets but, later hours of research, I really oasis't found a solution. Sorry if this is already answered.

Does settingoptions(shiny.maxReques tSize)to a big value not piece of work?

How-do-you-do Joe,

R:3.ii.3

Rstudio: Server editionVersion 0.99.893

shiny: 0.13.2

Bone: Linux

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

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

Two things to annotation:

• This error does not occur when I visit the app through chrome (i.due east. port 3838).
• This error does non occur when I effort locally (server.R and ui.R on my c drive), launching from the app Rstudio using Rstudio Version 0.99.1249, R 3.iii.i and shiny 0.13.ii

Cheers,

Steve

!?!? The base::options office takes ... parameters, so that error message shouldn't be possible. Unless maybe you lot're loading a bundle that masks the "options" part with a different 1? Tin you impress(environment(options)) and see what it says? (I'd look "<environs: namespace:base of operations>")

Thanks Joe!  I feel a bit sheepish that this issue was acquired by ii packages sharing a function proper noun merely I was thrown off by the fact that it ran fine through port 3838.

Is in that location a threshold for file uploads to a Shiny app that "should never exist exceeded"?

Not particularly. The file is streamed to a temp file every bit it'due south uploaded, and so it's actually a affair of how much max deejay infinite yous want to let one of these uploads to consume.
