There is no package called 'stringi'

[kquant]

Folks,
Any help on this configuration issue appreciated. It looks like stringi did not install with devtools

Running R version 3.2.2 (2015-08-14) on a Windows 6 through the Shiny interface

devtools::install_github("twitter/BreakoutDetection")
Downloading GitHub repo twitter/BreakoutDetection@master
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘stringi’
