In this setup "account has_many :consultations". Can anyone explain

stumped on how to reorder factors
I am trying to reorder a factor data type so that when I plot stats
associated with the factor, the ordering makes sense.
For instance, if I have a factor entered as follows ...
A = as.factor(c("1", "10", "3", "3", "10", "10"))
levels(A)

Bug with serialized columns in console ?
Hi,
I recently added 2 serialized columns in my class Server :
class Server < ActiveRecord::Base
serialize :visa, Hash
serialize :appli, Array

No problem in my controller and my application and everything works as
expected : Excel exports following the "visa" Hash or "appli" Array
are ok.
But since I added the visa Hash, I can''t load the record with

equivalent from gladder and ladder from stata
Dear community,
Apologies, I'm still pretty newbie. Anyway, I am performing linar regression
analysis. As a common cause of non-normally distributed residuals is
non-normally predictor variables, i'm interested in achieving the best
transformation of the predictors.
I've seen some commands at R, but I would like to know if it exists a
command equivalent to gladder (graphic display)

Migration Errors?

grabs data from an existing database and make them visible in a
structured form via browsers. So I thought that could be the right
