Answer 1

You might need to update your cacert.pem file. See here and here for links to other questions regarding this. I see this hasn't worked for other people using download.file(), but this might using Curl directly. You can update your bundle file like so:

system( paste0( "curl http://curl.haxx.se/ca/cacert.pem -o " , tempdir() , "/cacert.pem" ) )
#Then you can use it like so
twitCred$handshake( cainfo = paste0( tempdir() , "/cacert.pem" ) )
