Repost: Pluralization of non-noun names
...f it does it could be a one-to-many or a one-to-one
relationship. Is there a way to create new nouns in RoR so that I could
create the corresponding plurals like:
p_2quots
p_addrs
p_ccs
.
.
etc
and the system would work as normal?
Thanks,
Phil.

How do you detect if ActiveRecord ''update'' fails?
So I''m updating multiple model objects in one go with something like
this in my controller:
=> Photo.update(params[:photo].keys, params[:photo].values)
When the update fails due to validation errors, how do I detect it?
The Rails API says:
"If the save fails under validations, the unsaved object is still
returned."
So I can''t simply do this:

Multiple (7) Y axes?
...want the plots overlaid because it is the shape of
the graphs that I want to compare, not so much the values. I have found
examples where people show how to put two Y axes on the left of the plot
but I couldn't find examples of any more than that - is it possible?
Thanks,
Phil.

A trivial plot gives open circles as the plot char but another one gives me "q"s . . why is this?
...Rst",
ylab="ADf" )
I have tried adding the "pch=x" command with no effect . . what is
going on? (Both computers have the same fonts installed although the
home computer is Fedora 16 and the work one is Fedora 15). It is very
frustrating . .
Thanks,

Scaffolding - disabling Create, Edit, Destroy for some user logins?
...fore_filter :login_required

use the output of eg:

user logins in the corresponding view?
Thanks,

Strange result when backing up /etc vs /root
...TE="--delete"
.
.
rsync -av $DELETE --backup --backup-dir /delmod/$dt /etc /backup/
rsync -av $DELETE --backup --backup-dir /delmod/$dt /root /backup/
- only the changes to /root get backed up but ALL of /etc gets backed up
everytime! - why should this happen?
Thanks,
Phil.

2-D numerical integration over odd region
Hello all,
I'm hoping to find a way to evaluate the following sort of integral in R.
\int_a^b \int_{g(y)}^Inf f(x,y) dx dy.
The integral has no closed form and so must be evaluated numerically. The "adapt" package provides
for multidimensional integration but does not appear to allow the limits of integration to be a
function. I need to evaluate a number of integrals of this

numerical integration of a ftn of 2 variables
Dear R gurus,
To start, let me confess to not being an experienced programmer, although I have used R fairly
extensively in my work as a
graduate student in statistics.
I wish to find the root of a function of two variables that is defined by an integral which must be
evaluated numerically.
So the problem I want to solve is of the form: Find k such that f(k)=0, where f(y) = int_a^b
g(x,y)

...the cookbook eg, categories has_many recipes but in a book eg, book
has_one description - doesn''t that mean that the id of the description
