I tried to refer to http://shiny.rstudio.com/tutorial/lesson7/ and apply shiny::runGitHub() but face error. And then I tried to refer below sample to upload a copied set of ui and server files to main repo but doesn't help. Kindly assist?

I too am experiencing a similar issue.

Here is my code:

devtools::install_github("rstudio/leaflet")

devtools::install_github("ramnathv/rCharts")

install.packages( c( "ggthemes", "shiny", "shinydashboard", "geojsonio"
                    , "magrittr", "scales", "htmltools", "htmlwidgets", "DT"
                    , "dplyr", "stringr", "stringi", "MatchIt", "plotly", "censusapi"
                    , "ggplot2", "igraph", "networkD3", "pander" 
                    ) )

library( shiny )

shiny::runGitHub("USAspendingexplorer/USAspending-explorer")

My error message is as follows:

UPDATE: @englianhu @OmaymaS

My colleague Stephanie Wilcoxen (https://github.com/swilcoxen) figured out a solution!

When running shiny::runGitHub, the downloading url reads:

https://github.com/USAspendingexplorer/USAspending-explorer/archive/master.tar.gz

By simply copying that character string and replacing it with the ".../master.zip" extension, the following lines of code work :

devtools::install_github("rstudio/leaflet")

devtools::install_github("ramnathv/rCharts")

install.packages( c( "ggthemes", "shiny", "shinydashboard", "geojsonio"
                    , "magrittr", "scales", "htmltools", "htmlwidgets", "DT"
                    , "dplyr", "stringr", "stringi", "MatchIt", "plotly", "censusapi"
                    , "ggplot2", "igraph", "networkD3", "pander" 
                    ) )

library( shiny )

shiny::runUrl("https://github.com/USAspendingexplorer/USAspending-explorer/archive/master.zip")

Notice that the function shiny::runUrl was used in lieu of shiny::runGitHub.

Happy coding!
