Hi, I have a scenario where a doctor can have one or more specialties. For each doctor, one and only one of her specialties can be designated as primary. So I have tables called doctors, specialties, and doctors_specialties, the last of which has a boolean is_primary column. The doctor model class specifies that: has_and_belongs_to_many :specialties I want to enforce, at the lowest possible

Hi.....I am relatively new to R but was quite pleased with myself at having generated a series of lattice plots as PDFs. I was very surprised when plotting these out as jpegs (or png or tiff) that the strip title information above each lattice plot vanished. The pdf was fine. Has anybody any ideas? I can't add an image as the information is sensitive. Many Thanks Steve Creamer Here is the

I trying to create a select using Arel but I''m passing three parameters, I want to include the parameters only if they are different to nil or blank. Here is my method: def self.advsearch(summary_description, specialties, place) User.joins(:experience,:summary,:information) .where(Information.arel_table[:business].eq(false))

Hi all, I am very confused with class. I am looking at some weather data which I want to use as explanatory variables in an lm. R has treated these variables as factors (i.e. with different levels), whereas I want them treated as discretely measured continuous variables. So I need to reassign the class of these variables, right? Indeed, doing class(southwest$pressure) (pressure being air

Greetings! I am trying to figure out how to order a data frame by one variable conditioned on another. Here is an example of what I have: d <- data.frame(RUN = rep(1:3, each = 3), ID = 1:9, AUC = runif(9,1,100)) > d RUN ID AUC 1 1 70.2 1 2 86.5 1 3 20.1 2 4 74.3 2 5 53.6 2 6 67.6 3 7 99.9 3 8 47.3 3 9 41.3

Hi All I dont know if anyone else has noticed the same thing, but with 2 subsequent runs of the same syntax, I am getting exactly the same results. I was expecting that results differ slighlty, say in the 4th or 5th decimal place. Is this a specialty with R2WinBUGS? Does it have something to do with the seed value? Isnt the seed value reset everytime I restart winbugs? Thanks Toby

I've been working my way through the softphones listed on voip-info over the last few weeks and I've not really found anything to fit the bill. Has anyone had more luck? The environment is a small call centre of 5 users. Operators often need to be able to transfer calls to other operators with different specialties, so the softphone needs to be easy to use and quick to transfer calls.

Hi Everyone, I am trying to understand the unstack() function but after struggling for two days, I have given up. More specifically, I am trying the exercises at the end of Chapter 1 of Data Analysis and Graphics Using R by Maindonald and Braun, 2nd ed. Exercise 18 (p. 41) asks to unstack the Rabbit data frame from the MASS package to get a certain data frame that is shown in the exercise.

hi, just wanted to introduce myself. My company is currently running a very old version of Samba - 2.0.7. I have been upgrading our UNIX systems this past month and have reached Samba. I know, if this is anything like the past upgrades over the last few weeks, I will need some support. Nothing has installed successfully the first time around. I downloaded version 3.0.4 and will be

I've been reading the R mail archives and I've found a lot of messages with this same kind of problem, but I can't understand the answers. Can one of you try to explain this to me? Here's my example. Given a regression model and a variable, I want to use unstack() on the vector of residuals and make some magic with the result. But unstack hates me. PCSE <- function

Folks, I have the following dataframe: > x <- structure(list(name = c("EU B", "EU B", "EU B", "EU B", "EU B", "EU B", "AU A", "AU A", "AU A", "AU A", "AU A", "AU A"), date = c("2010-10-11", "2010-10-12", "2010-10-13",

I am just assuming this can be done, but I have not gotten close to making it happen. I have a data file with about 1 million rows with 1470 unique subjects. Each row represents a small set of observations made on a specific date for a single subject. I would like to transform the data so that I have an R object with a single entry for each subject and start date and vectors for the

NetWare 6 sp4 server to windows 2000 server using cwrsync 1.2.1 when the cwrsync service writes the files to the server it uses it's own username and permissions. Does anyone have any suggestions as to how I can get this to write the files so common users and delete and change stuff? would the perverse permissions work with windows? Thanks, Matt Vorwald Network Engineer Lumber

I have a simple Rails 4 project with two scaffolded models: Practice and Practitioner. I have set these both as habtm and am in the process of adding checkboxes to the Practitioner form so that I can check off the practices that this practitioner belongs to. In the practitioners_controller, I added practice_ids to the practitioner_params permit list, but I am still getting the error: Started

Hi I am evaluating some voice broadcasting solutions based on Asterisks for more than 1000 simultaneous calls. Connection to Asterisk all are based on SIP and SIP Trunks so no DAHDI hardware is required. According to some recommendations like http://osdial.org/howto/? "Internal timing is very critical with Asterisk when it is under load" and we must use DAHDI hardware or "USB Voice

yes, thanks, and I was getting close to that. One thing I found is the manual says the height is the distance above the y-line, which should be, but doesn't have to be positive. In fact, the time series are estimates of a cycle, and has negative values, which unfortunately are not included in my sub-sample. And the negative values are not handled properly (the series disappears for

The min_height = -0.25 is there to make it show cycle values down to -1/4. You may want to change it to -1 so it shows more of the cycle values.

Hi Everyone, I've got kids who are growing older and I want to build a Linux box to filter Internet access. I've got six computers on the Internet, plus the laptops -- most run Windows. I'm not sure if it's called a router or gateway or...? I don't mind doing the leg work, I just don't know where to start. I'm pretty sure I'm *not* looking for a web server (though

I have a data set similar to this: P1id Veg1 Veg2 AreaPoly2 P2ID 1 p p 1 1 1 p p 1.5 2 2 p p 2 3 2 p h 3.5 4 For each group of "Poly1id" records, I wish to output (subset) the record which has largest "AreaPoly2" value, but only if
