R help - Jul 2015 - R 3.2.0 - Windows 8, 1 - SSL certificate problem installing course in swirl

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

We don't know what "install_from_swirl" is doing, so it's hard
to say.
You should ask its author.

If it is using the "wininet" method to download from an https site,
then
it is Windows that is issuing the error:  you may be able to configure
Internet Explorer to avoid it.  Ask Microsoft how.
