Hello,
I tried to source a function from a github R.script to my local working repository using your proposed "source_https" function, but it reported an error. For instance, if I run the code as follows to source your source_https.script, it reported:
Error in function (type, msg, asError = TRUE) :
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

Do you have any idea about this error?
Thanks in advance,
Qing
