[R] R 3.2.0 - Windows 8, 1 - SSL certificate problem installing course in swirl

[MH]

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
