I'm trying to call BUGS from R. But it's not working. R freezes up and BUGS gives me a strange output in the log. Just to know, BUGS is registered. The modified date on the keys file is today (Dec. 9th). It should be fully registered so that I can use it fully. And, the BUGS model is syntactically correct. Any suggestions would be very helpful. Here is my BUGS model: model {

Hello everyone, I was asked to repost this again, sorry for any inconvenience. I'm looking replacement for ddply function from plyr package.

Is there any available solution which allow me to apply function by category?

Hi, I''m trying some RJS to update a series of list boxes in which the user selects a state, and the following list gets updated with a list of counties, and the same for the next list of areas. My code works perfectly (albeit a bit slow) on Firefox, but on Internet Explorer it clears the list box (instead of filling it) and Netscape shows all the counties cramped together on one

Hi friends!

I have been using multiple observers, i.e., observe_field(), on the same input field and relying on them to execute in the same order that they appear in the page.
