Hola, Esta pregunta la hice en stackoverflow <http://stackoverflow.com/questions/31137940/randomly-assign-teachers-to-classrooms-imposing-restrictions/31143808#31143808>pero nadie pudo contestarla. 1. Quiero generar N escuelas, con G grados y C divisiones. 2. Quiero asignar cada uno de T maestros a 2 divisiones en un grado y escuela Si tengo C=4 divisiones, puedo lograr lo que quiero con

Hola, 0. La falta de 'elegancia' hace que sea mas dificil hacer cambios al codigo. Por ejemplo cambiar n.classrooms <- 4 a n.classrooms <- 20 1. Cuando tengo solo 4 puedo hacer esto: schoolGrade$A <- Teachers$Teacher.ID[1:cuttoff1] schoolGrade$B <- Teachers$Teacher.ID[1:cuttoff1] schoolGrade$C <- Teachers$Teacher.ID[(cuttoff1+1):n.teachers] schoolGrade$D <-

Gracias Carlos, Tu codigo es un gran paso en el sentido correcto pero no produce exactamente lo que estoy buscando. Mi "solucion" en stackoverflow <http://stackoverflow.com/questions/31137940/randomly-assign-teachers-to-classrooms-imposing-restrictions/31143808#31143808> produce un data frame `schoolGrade` con 240 observaciones y 7 variables. Mi objetivo es poder generar un data

Perdon por no se lo suficientemente claro :( Tu codigo produce `validPairs` que tiene 7 variables y 360 observaciones. Donde > validPairs[1,] V1 V2 V3 V4 V5 V6 valid 60 e1 g1 c1 e1 g1 c2 Valid indica que un maestro tiene asignado c1 y c2 en la escuela e1 y el grado g1. Correcto? Si es asi, esto es casi lo que queira producir y creo que puedo llegar a donde quiero usando tu codigo de base.

Hello, Is it possible to have several HABTM-relationships for the same object? Example: Imagine I have 3 objects (classroom, student, teacher) and define the associations for the student as: class Student < ActiveRecord::Base has_and_belongs_to_many :classrooms has_and_belongs_to_many :teachers class Classroom < ActiveRecord::Base has_and_belongs_to_many :students class Teacher <

Hello, I have a simulated data structure in which students are nested within teachers, and with each student are associated two test scores. There are 20 classrooms and 25 students per classroom, for a total of 500 students and two scores per student. Here are the first 10 lines of my dataframe "d": studid tchid Y time 1 1 1 -1.0833222 0 2 1 1

My school district will be building a new elementary school in 2006. We were about to go to bid with a traditional intercom system for the campus but I would like implement Asterisk at the campus. My question is, do we build in a traditional intercom/paging system and tie that into the Asterisk PBX, the way such intercoms have been connected to other PBX's in our district in the past, or

I've got a table of 1 row per observation. 16 questions * n subjects * 4 classrooms (2 teachers * 2 conditions) I'd like to run some simple regressions that look something like this: lm(length ~ elapsed) I'd like to do the regressions several times, split out by questionkey, student, class. What I've been doing is using a series of which's to create new data sets (e.g.

Perhaps this is intentional, but it seems unlikely: class Person < ActiveRecord::Base belongs_to :school end p = Person.find(:first) p.school # nil p.school_id = School.find_by_name(''High School'').id p.school.name # High School p.school_id = School.find_by_name(''Primary School'').id p.school.name # High School <= Shouldn''t this be Primary

I am trying to setup Samba in a classroom so that a student's samba folder can be accessed via Windows by the student and the teacher. I have Samba working, but can only get the student access to the folder. How can I add another user or group to Samba so the teacher and student have full control over the folder? Thanks Tom

Dear R People: I am using R for teaching purposes in a large classroom. Each computer has its own copy of R. However, every once in a while, about half of us will get thrown out of R, for no apparent reason. By the way, it has happened in other classrooms as well. Has anyone else run into this, please? If so, how have you solved this problem, please? Thanks in advance! R for Windows

I have a weird problem going on. All of sudden, records for a certain model will not save with #save Please take a look at this: >> p = Payment.new(:payment_reason_id => 1, :payment_method_id => 1, :date => Date.today, :amount => ''5.00'', :payable => Student.find(608)) => #<Payment id: nil, school_id: nil, payment_reason_id: 1, payment_method_id: 1,

Hi All I was wondering if I can avoid a time-consuming for loop on my 600000 obs dataset. school_id y 8 9.87 8 8.89 8 7.89 8 8.88 20 6.78 20 9.99 20 8.79 31 10.1 31 11 There are, say, 143 different schools in this 600000 obs dataset. I need to thave sequential identifiers, 1,2,3,4,5,...,143. I was using an

I am looking at using Shorewall in a local college. There will be a default set of firewall rules, but for some lessons certain classrooms will be granted full Internet access (this will be done by the lecturer via a web interface). I am seeking suggestions for the best way to implement this under Shorewall. I think it might make sense to make each classroom a separate zone, but is there a dynamic

I have two tables that have a HABTM relationship: Teacher has_and_belongs_to_many Groups, and Group has_and_belongs_to_many Teachers. This is what I want: select a Teacher, and then drag Groups from one box to another to assign them to the teacher. Or, select a group, and drag and drop Teachers to assign them to groups. All using AJAX, (off course). Only problem is, I don''t know

Xen List After planning for a year to move my Xen 3.4 classrooms to XCP I''m now making an effort. With the old system I wrote many lines of bash scripts around the xm command to group and manage my VMs. I used sudo to grant privileges for each student to start, stop, console into, reboot, and wipe their VMs without any interaction from me. Now with XCP I had the hope of moving to the

Hi All, Has anybody seen (Hopefully solved ;) this problem? We're running samba 2.2.8a as a PDC for windows classrooms with an LDAP backend. What's happening is that users are waking up the windows machines by pressing the space bar and then logging in. They authenticate successfully (leading spaces ignored) but windows is miscreating the roaming profiles with leading spaces which
