how do I name data frames and files according to the index of a for loop?
Thanks in advance for reading my question.
This is my first time working with R, though I have some intro-level
experience with other languages.
I am writing a program that performs a certain set of calculations on
each row of a list of data, and here's what I have so far:
for (i in 1:2858) {
Calc_1 <- some_stuff
Calc_2 <- some_more_stuff

Changing default date format in Rails
I''ve spent all day digging through the rails api and postgres-pr on
this, I think it''s time to ask the list.
Postgres stores a Date in YYYY-MM-DD format. My users want the dates
in MM/DD/YYYY format.
Sure, I could explicitly convert it on the app level every place where
a date is displayed, but that seemed like a DRY violation.
I thought I''d be clever and simply

Using <%= text_field %> within partials is problematic
All,
Thanks for any help in advance.
I have what I think is a very straightforward partial template and I
can''t figure out why a text_field call within it doesn''t work.
Here is my calling template: lists.rhtml
<div id="target_lists">
<%= render(:partial => "target_lists", :collection => @target_lists)

Implementing HTTPS with WEBrick?
All,
I would like to test some secure pages that I''m developing in my
WEBrick-based development environment.
I''ve done some research and it appears that I need to create a new
command that will start a HTTPS based WEBrick server. Is this correct?
Also, it appears that the https.rb module is not included with the
WEBrick bundled in Rails. So, I will need to go get that

Custom view helpers
Hi all,
I would like to write some custom helpers like the ones available as
form helpers text_field, text_area and the like. My first try was this:
custom_helper(obj, meth)
''some_string'' + obj.send(meth) + ''some_other_string''
end
Object and method are being passed as symbols like this:
custom_helper(:person, :name)

Wrap error_messages_for() call when no instance var present
I am trying to put some smarts around a call to
<%= error_messages_for %>
so that when I first come into this page i.e. when my instance variable
@target_list has not been defined yet, the page doesn''t break.
I''m doing this:
<% if @target_list? %>
<%= error_messages_for ''target_list'' %>
<% end %>
I get a syntax error on line 1.

Generic page element display initializer in a layout?
All,
I''ve run into a snag. I need to handle the display of elements on my
page and I want to use my Javascript event handlers on page load.
However, my BODY tag is trapped in my generic layout.
I''m thinking that I can put an onLoad on the BODY tag that will just
call a Javascript method called initializePage() and then provide this
initializePage() call in my specific page

Form validation - keepin correct fields displayed on refresh
All,
I''m finally doing my first real form in Rails - the model object that
I''m entering information for has 8 validations so far.
If I type in good values for all the fields but one, I get the pretty
validation, and the nice field highlighting, but all of the fields are
cleared, forcing me to retype all of that info. That is a big drag.
Is there a standard way to get the

Setting a global before_filter action in application.rb
Can you set a global before_filter action in application.rb?
So, for example, you could control authentication for all of the
controllers in an app.?
Obviously, you would need a way to reference actions by controller
within this "global before-filter".
Thanks,

Setup new data in the test database _after_ unit test runs

I want to run automated unit tests as part of my build. I am building

into my test database that will act as fresh "system test" data for my
users to play with.
What is the best way to "load the standard system test/user acceptance

"mysql" 2.7.3 gem install for Windows appears incomplete
When I install the 2.7.3 "mysql" gem on Windows XP (trying to prepare
for the requirement to use the mysql gem in Rails 2.2.2) by using:
gem install mysql
I get a mysql-2.7.3-x86-mswin32 directory under gems, but underneath
that, only a docs directory, an ext directory, and README, Rakefile and

I then cannot do any connecting to my MySQL databases.

What is has_many :through really buying you over HABTM?
So having just learned how to do has_many :through as opposed to HABTM,
and then, being concerned that I wouldn''t get it to work, I started
thinking about these two approaches.
It seems to me that the _only_ problem that the HM:T (has_many :through)
approach solves that HABTM doesn''t is the issue of the potential
collision of id columns between your join table and one of

Specify a controller action via attribute in INPUT tag?

I would like to add another <INPUT type="submit" ...> to my form.
How do I successfully associate that <INPUT> tag with a different
controller action than the default one specified by my <%=

Or does this approach even make sense?

Does text_field go directly to attributes hash in AR object?
All,
I''m having a hell of a time figuring out what is going on here.
I''m trying to override one of my getters so that I can format it a
certain way in my form. But I can''t seem to get text_field to call the
appropriate method on my object.
So here''s my getter:
