Zipf fitting using R
Dear R-users,
I am new to R and would like to use it for fitting the zipf distribution to
some numeric data that I have. Here's the snippet that I use:
library(VGAM)
X <- read.table(file("~\\mydata.txt", encoding="latin1"))
w <- as.vector(t((X[2])))
w <- w/sum(w)
y <- (1:length(w))
fit = vglm (y ~ 1, zipf, tra=TRUE, weight=w)
zipf(N=NULL,

Easy way of dealing with nil properties in templates?
Is there an easy way to deal with nil properties in
templates? All I''m aware of are these methods, and
it''s quite tedious and surely violates DRY.
<%= @member.name unless @member.name.nil? %>
<%= @member.name.to_is %>
<%= "#{@member.name}" %>

Redirecting in a view?
Is there a way to do this in a view?
<% redirect_to ''http://url.com'' %>
All I can think of is outputting a link and using
Javascript to click it, or probably do something like
''doc.location(url)''.

Just about to set up RoR on our server and was wondering what the

Any guidance would be helpful!

Page caching feeds and cache file extensions
I have a feeds controller which generates RSS and Atom pages. I put
''caches_page :show'' in it. The problem is that the pages are saved with
an html extension. As a result, browsers display the cached feeds as
HTML rather than XML, and feed validators complain.
There''s an option to set ''Base.page_cache_extension'' globally, but I

categories and admin/categories - different controllers and templates?
Is there some way to have these two sets of URLs use
totally different controllers and templates?

plotting Zipf and Zipf-Mandelbrot curves in R
Using R, I plotted a log-log plot of the frequencies in the Brown Corpus
using
plot(sort(file.tfl$f, decreasing=TRUE), xlab="rank", ylab="frequency",
log="x,y")
However, I would also like to add lines showing the curves for a Zipfian
distribution and for Zipf-Mandelbrot.
I have seen these in many articles that used R in creating graphs.
Thank you!

Difficult process of restarting SCGI, Lighttpd, Apache, sessions
I''ve managed to get Rails working using Apache->Lighttpd->SCGI. Restarting everything is really
difficult. This appears to be the process:
- stop apache
- stop lighttpd
- stop scgi
- make sure scgi still isn''t running (it sometimes does) - if it is, kill it
- delete all session files (they often cause permission errors)
- start scgi
- start apache
- start lighttpd
- cross

undefined method `include''
I''m getting this error in Rails:
undefined method `include'' for
#<MenusController:0x408efd1c>
The offending code is:
require "rexml/document"
include REXML
I see there may be a problem with GCC 4 on OSX, but
I''m using Redhat with GCC 3.2.

Zeta and Zipf distribution
Dear R user,
I want to estimate the parameter of ZETA or/and ZIPF distributions

Otherwise do you know a function (which use MLE method to estimate
distribution parameters) that allow me to specify a

ruby-forum.com problems?
Anybody else experiencing problems accessing
ruby-forum.com ? For the past week or so I''ve mostly
not been able to access it. It either never loads, or
displays a 500 error message. I prefer it though to
direct email, or the Mailman archives.

Dedicated Host Recommendations?
I currently have a dedicated server at ev1servers, but
it''s getting rather antiquated (Redhat 9) and am
looking to upgrade. I''m thinking about serverbeach.com
- one of their CentOS servers. Anybody have any
recommendations for dedicated servers on which to run
Rails? Hopefully less than $200/month.
Thanks!
