I encountered the following error when trying to install shinyapps on my ubuntu 13.04. Can anyone help? Thanks.
Call:
require(devtools)
devtools::install_github('rstudio/shinyapps')

Answer 1

Please have a look at the parameter list of install_github. Your call should be
install_github( repo = "shinyapps", username="rstudio" )
At least for devtools prior to version 1.4.1: https://github.com/hadley/devtools/blob/master/NEWS.md

Answer 2

I think you have another choice. Please download the package from https://github.com/hadley/rstudio/shinyapps/archive/master.zip to your local computer. Then install the package by call install_local(). For example,
install_local("~/Downloads/shinyapps-master.zip").
shinyapps-master.zip is the shinyapps package, and ~/Downloads/ is the path.

Answer 3

shinyapps package has been replaced by rsconnect which can be simply installed through CRAN in the regular way.
