First of all my question is very related to
How to host Shiny apps on windows server?
But, it seems that i need some more reputation to comment in other posts....
My problem/question: I have a shiny app that i want to deploy and make available for people in my department. The paid version of shinyapps.io is not an option for now at least, so i am looking for alternatives. I am working on Windows and this is a problem from what i understand in order to host my own server. I tried the solution provided here, but i get the following error:
"Error in makeTcpServer(host, port, appwrapper$onHeaders, appwrapper$onBodyData, : Expecting a single value: [type=character; extent=5].
Also, another solution is shinyproxy. But it is rather complicated to set it up and i didn't find anywhere how to do that on Windows 10 Home edition ( so no Hyper-V availability...). If you are aware of this, please let me know!
I would appreciate any help to figure it out!
Thanks, Giannis
I guess the regular expression finds 2 values for IPv4 and is storing them in the z value.
Run this and check how many Ip-adresses it returns:
x <- system("ipconfig", intern=TRUE)
z <- x[grep("IPv4", x)]
z
If the print statement looks like this, it wont work:
print(z)
1 " IPv4-Adresse . . . . . . . . . . : xxx.xxx.x.xxx" IPv4-Adresse . . . . . . . . . . : x.x.x.x"
You will have to decide on one of them. In this example i am taking the second Ip-Adress ( z[2] ): I also changed "launch.browser = FALSE" to TRUE, so that the shiny-App opens in the browser.
ip <- gsub(".*? ([[:digit:]])", "\\1", z[2])
print(paste0("the Shiny Web application runs on: http://", ip, ":1234/"))
runApp(folder_address, launch.browser=TRUE, port = 1234, host = ip)
Do you have a local Linux Server in your department? You could easily upload it there, using the Open Source Version of Shiny Server
