HI, Dear R community, Last friday, I used the codes, it works, but today, it does not run? > fit.dimer <- rpart(outcome ~., method="class", data=p.df) Error in `[.data.frame`(frame, predictors) : undefined columns selected DOEs anyone have comments or suggestions?

I am running asterisk 1.4 and the Digium GUI SVN-branch-2.0-r4489. When one phone calls another, I see the following on the console (here, 6223 dials 6123) -- Executing [6123 at DLPN_DefaultDialPlan:1] Macro("IAX2/6223-10489", "stdexten|6123|SIP/6123&IAX2/6123") in new stack -- Executing [s at macro-stdexten:1] Set("IAX2/6223-10489",

Hello, Some of my users have phones lacking a DND button. I need to provide an extension they can dial that will put them in DND, i.e. tell the server not to send them any calls until they get off the DND. I've researched it for almost 3 days now and tried a range of configurations. I'm hoping somebody here has an answer. Currently, I have this in extensions.conf [app-dnd-on]

...the Direct method, Explicit tau-leaping, Binomial tau-leaping, and Optimized tau-leaping. The package also provides a library of molecular, ecological and epidemiological example models (as demos) that can easily be customized and extended. Currently the following models are included, Decaying-Dimerization Reaction Set, Linear Molecular Chain System, single-species logistic growth model, Lotka predator-prey model, Rosenzweig-MacArthur predator-prey model, and Kermack-McKendrick SIR model. The release consists of several bug fixes, improved documentation, and a revised more 'R-like'...

Hello, I have a fairly standard call center. I'm running 1.4.23.1. I am trying to get a mechanism where : 1- Employee A can have the phone at his desk ring when a call comes in the queue 2- When already on a call, employee A does not hear a "beep" in his phone because another call is trying to come in It's fairly simple. I tried a few different things: in queues.conf [559]
