yes, they are the same, the ryc line is for more classic standard yarns, while the Rowan label has some standards, like cotton glace, but also some funky yarns that go into production for a couple of seasons (cotton braid, glimmer print, holiday, cotton rope, cotton tape for ex) and then are discontinued in favor of a new interesting kind of yarn.
Mostly, I've noticed that if the yarn has its own pattern book and is not prominently featured in the Rowan Magazines, it's a 'funky' yarn that you should buy up while you see it, because it may not last very long
