Hello,
I try to install a course for swirl and got a SSL problem:
> install_from_swirl("R Programming")
Error in function (type, msg, asError = TRUE) :
SSL certificate problem: self signed certificate in certificate chain
Found this answer with Google but does not work either:
> set_config( config( ssl.verifypeer = 0L ) )
Error: could not find function "set_config"
What do I do to avoid or accept the SSL certificate?
Kind regards,
Martin
