Install shiny on Windows 7

[Wang-Cankun]

When I first typed
shiny::runGitHub("iris", "btmonier") on Rstudio, I got the error in the console that I haven't install the 'httpuv', after I manually installed httpuv package, I got the following error:
> shiny::runGitHub("iris", "btmonier") Downloading https://github.com/btmonier/iris/archive/master.tar.gz Error in utils::download.file(url, method = method, ...) : cannot open URL 'https://github.com/btmonier/iris/archive/master.tar.gz'

When I load the iris from desktop:

library(shiny)
setwd("C:/Users/flyku/Desktop/iris")
runApp()

The error:

Loading required package: Hmisc
Error: package or namespace load failed for ‘Hmisc’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 there is no package called ‘checkmate’
Loading required package: geneplotter

Error: package or namespace load failed for ‘annotate’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):

after I installed all the dependencies, the browser says:ERROR: An error has occurred. Check your logs or contact the app author for clarification.
