<html><body><div>Brian - Get over yourself! That was an A++ response in terms of being <span style="color: #000000; font-family: SFNSText, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; display: inline !important; float: none;" data-mce-style="color: #000000; font-family: SFNSText, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 15px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 300; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; display: inline !important; float: none;">obnoxious, smug and condescending. </span>I wasn't looking for anyone to do any internet searches high atop their Ivory Tower, it was a simple question that I was hoping someone had a similar experience with. Trust me, I've done plenty of searches on this topic and my "google fu" skills are on par with yours. I saw the same inquiry you probably saw w/ your search results, but the user with my problem never confirmed if he figured it out despite asking a couple of times on the thread. If he's asking the same follow-up question more than once then chances are he never got it working. </div><div><br data-mce-bogus="1"></div><div>As far as "hijacking the thread" it was a simple post that seemed appropriate for the topic but I am so sorry if I offended you, or anyone else, for breaking the unwritten rules. Look, I've been an R user for 2.5 years but my skills are nowhere near 90%, hell maybe 100% of the people here -- if I were to post this as a standalone question there wouldn't be a single response. Half the subscribers would be laughing behind their keyboard. Posting here is only a matter of last resort, so sometimes you gotta take your shot. <br></div><div><br data-mce-bogus="1"></div><div>PS - I did figure it out though, all of the packages were properly installed so that wasn't the problem....and thankfully I'm not crazy! But it was a simple fix in hindsight and I'm sure all of you experienced it at one point or another </div><div><br data-mce-bogus="1"></div><div><br>On Sep 20, 2016, at 08:33 AM, "Brian G.
