Error message when installing on clean R instance

[StijnKas]

I had trouble installing on a new device with a new R instance, I got the following error message:

> library(devtools)
Loading required package: usethis
> install_github("pegasystems/cdh-datascientist-tools/r", build_vignettes=TRUE)
Downloading GitHub repo pegasystems/cdh-datascientist-tools@HEAD
Error in utils::download.file(url, path, method = method, quiet = quiet,  : 
  download from 'https://api.github.com/repos/pegasystems/cdh-datascientist-tools/tarball/HEAD' failed

I found this GitHub issue describing the solution that worked for me: https://github.com/r-lib/remotes/issues/130#issuecomment-735354677

Adding this line of code made it work without any issues:

> options(download.file.method = "libcurl")
> install_github("pegasystems/cdh-datascientist-tools/r", build_vignettes=TRUE)

Perhaps we could add this line to the install instructions, or even add the 'libcurl' method to the install_github command directly.
