install fastcmprsk package

[hzhao_liu]

I need to use the package fastcmprsk to run a prediction model. However, this package is removed from the CRAN repository in the current R version. I tried to use the following codes to install it:
remotes::install_version("fastcmprsk", version="1.1.1")
It failed with the following error message (I typed the error message since I can't copy and past it from R to this page. It may contain typos):

Have you installed RTools?

@hzhao_liu

since I can't copy and past it from R to this page

why not? Retyping all that with so few typos was a heroic effort, thank you

@hzhao_liu

remotes::install_version("fastcmprsk", version="1.1.1")

I install Rtools43 installer on my computer: Rtools43 for Windows

[hzhao_liu]

Thanks for your response. I installed Rtools43 for Windows. After I download it to my computer, I restart the computer. Then, I use the codes to install fastcmprsk package. It works this time.

Problem solved. Thanks a lot!
