Shiny tutorial lesson 6: getting error

Question

I am trying to run the shiny tutorial 6 app, from shiny-Rstudio website. The url is :

http://shiny.rstudio.com/tutorial/lesson6/

While trying to run the app, I am getting below error:

Error : Failed to download file. Error message:
cannot open URL 'https://research.stlouisfed.org/fred2/series/CPIAUCNS/downloaddata/CPIAUCNS.csv'

I am new to shiny and do not understand this error.

Post your code, where do you receive this error? – demonplus Feb 12 '16 at 12:45 — demonplus, Feb 12 '16 at 12:45

Found the answer in other thread in stack-overflow:

Quantmod Error 'cannot open URL'

The code that should be used to run the app for lesson 6 is:

library(shiny)
options(download.file.method="libcurl")#This fixed the error
runApp("stockVis")

make sure you have saved server.R, ui.R and helpers.r in a folder named "stockVis". If it's ok, you could try to specify the path of the app, like this :

library(quantmod)
runApp("D:/mydocuments/stockVis")
