Apologies, the issue is actually to do with the version of R

• package ‘emh’ is not available (for R version 3.5.2)

Please help and advise that I cannot install your package. Thanks.

library(devtools) suppressMessages(install_github(repo="stuartgordonreid/emh",force = TRUE)) √ checking for file 'C:\Users\Weihan Liu\AppData\Local\Temp\RtmpEzG8O9\remotes526c3af7493a\StuartGordonReid-emh-52a408c/DESCRIPTION' ...

• cleaning src

Accordingly, I encountered the following error message:
