LOL dennis, thanks for the laugh at the end. I'm a PhD student... I had never used it before until this last semester when i started taking Bayes at my new university (transfer because of husband's job =\). My old dept offered bayes, but not the new one, so i am taking it in the psychology dept.... the application (lots of binary outcomes and t-test focused) isn't terribly useful for my own discipline (poli sci, where ALL i do is LM and logistic and now HLM!) but it -at least- has exposed me to how to use bayes, JAGS, etc. so it isn't completely foreign to me. I am on a mac and, for whatever reason (until the latest update), I was NEVER able to run any code on it. it was always always locking up on me.... everyone else in the class was using it (we use the Kruschke book and he has code, etc and recommnds it) so I was determinded to get it to work.... always ended in HOURS and HOURS of frustration and me just saying *screw it* and going to R and completing the task in 30 minutes. =b but like i said, since they have updated it (was in Jan of Feb?), i haven't had any issues but, MAN was that a frustrating 5/6 months. it really put a sour taste in my mouth. but, i will say- thank god for R-studio right now. lol totally saved my sanity. but i am determined to fix R...

thank you, dennis, but that's ok! i ran it all successfully yesterday, as well as my own.... any ideas why it would blow up like this and not plot?
Sorry, no. Given the tenor of some of your posts today, I wondered if your computer had contracted a virus. Progressively weird behavior is often a sign, as is a noticeable slowdown in performance.
what's interesting is: was able to run my own research just fine (JUST NOW finished) in R-studio (YUK!!!!), so something is definitely corrupt in the R environment. I wish I could figure it out! i HATE using R-studio. =\
I have certain issues with it, but I like RStudio for documentation writing and I'm about to start package development using RStudio projects in conjunction with Git. If you use script files instead of typing at the command line or copy/pasting from a text editor, it's easy to bounce back and forth between the two; the only thing I miss is the 'Run selection' feature in R GUI script shells running under Windows. If you're an R package developer, it's definitely the way to go, especially if you're using Git and devtools. Why do you hate RStudio so much? (I'm envisioning a Sanka commercial with Robert Young from the 70s where the commercial opens with the line: Hey, why so tense? :) [I can guess why, but I'll leave it at that.] To quote the great psychologist Cesar Millan, stay calm and assertive :) Dennis
