Mapping to BigDecimals instead of Floats
Hi everyone,
I''m new to Rails and Ruby, and have been working my way through the Pickaxe
and Agile Rails books for the last week or so. With a background in payroll
apps I found that the default ActiveRecord mapping of decimal columns to
float variables really bothered me! Financial calcs need high levels of
accuracy and floats just don''t give you that.
I know there are a bunch

AJAX Form, :postion => :bottom but replace when error?
I have a form below a table to add new notes to an item. If the note
does not have a title or body, the note is not saved and a form error
is displayed. However, if the note validates successfully, then the
note is added to the bottom of the table above. Just for reference,
the table id is "note_list" and the add form div is id="note_add_form".
So, my problem/question

Jobs at the University of Auckland
We have two lectureship positions advertised at the moment.
One (or both) of these is intended for a specialist in statistical
computation. The salary doesn't look great by international standards
but there are compensations: housing is cheap, the air is clean,
and the worlds problems are far away. We also have a track record
of getting tenure for computing people.

Add rank column to data frame as in SQL...
Hopefully this is an easy problem...
I'm trying to add a partitioned rank column to a data frame where the
rank is calculated separately across a partition by categories, the
way you could easily do in SQL. I found this solution in the archives
that looked like it might work:

Comparison of aggregate in R and group by in mysql
Hi, netters,
First of all, thanks a lot for all the prompt replies to my earlier question about "merging" data frames in R.
Actually that's an equivalence to the "join" clause in mysql.
Now I have another question. Suppose I have a data frame X with lots of columns/variables:
Name, Age,Group, Type, Salary.
I wanna do a subtotal of salaries:
aggregate(X$Salary,

order to change value of one attribute in given record. I use this code
to invoke a method from controller:

My method looks like this (just a simple one - to set the

Formatting of numbers on y axis
Hello all. I have the following:
plot(salaries$yearID, salaries$salary, type='n', xaxt='n', xlab='',

axis(2, axTicks(2), format(axTicks(2), scientific = F))
Which nicely creates the Y axis with the raw numbers, which are in the range
of .5 - 7

JOIN conditions
Hi,
how can I get Rails to generate SQL queries with conditions in the JOIN clause?
What I would want is:
SELECT * FROM people p
LEFT OUTER JOIN jobs j (p.job_id = j.id AND j.salary > 9999999)
I tried
People.find(:all, :include => ''jobs'', :conditions => ''jobs.salary > 9999999'')
but that generates
SELECT * FROM people p

Currency symbols in Xtick or Ytick labels
How do you label Xtick and Ytick marks with Currency symbols: $2000
instead of 2000? I would like to add dollar symbols to tickmarks on
boxplots, histograms and back-to-back histograms.
My Examples (requiring the lattice and Hmisc packages):
data(case0102, package="Sleuth2")
str(case0102)
boxplot(Salary~Sex, case0102)
histogram(~ Salary | Sex, data=case0102)
