HTML Fragment not Loading in Firefox; Fine Elsewhere
Ok, this has got me going a bit crazy. I have an HTML fragment being
returned for the result to an AJAX query. It works fine in Safari or
from curl (and even in IE/Mac), but utterly fails to load in Firefox,
even if I point directly to the URL, skipping all that AJAX stuff in
between. (The server logs show a 200 response, regardless of which
browser is being used.) I''ve verified

Getting Index When Using render :partial
I''m using a web service to retrieve an array of results to a search
and a render :partial to display those results to the user, while at
the same time putting the results into the session. Is there a way
for my _book.rhtml file to have access to the index of the result
currently being displayed, like each_with_index makes available to
its block? This would allow me to have the

Re: Getting Index When Using render :partial (Benjamin Stiglitz)
Thanks for the suggestion, Ben. This seems an excellent approach to
the problem, except that I''d been under the impression that one could
only call render once. If you call it multiple times as the
each_with_index loop iterates, are the results just combined
automatically? How does that work?
Thanks!

Reading multiple text files and then combining into a dataframe
I have a multiple text files, separated by a single space, that I need to
combine into a single data.frame. Below is the track I'm on using
list.files to capture the names of the files and then lapply with
read.table. But I run into problems making a usable dataframe out of the
data.

State of the Art in Login?
Hi folks,
I''ve got an older project I''ve used LoginGenerator for. It works pretty
well, but lacks password resetting, etc.
Now I''ve got a new project for a client that''s going to need login
capabilities as well. I''ve been looking at the Salted Login Generator
and the Login Engine, and have taken quick stabs at running through the

matrix into vector with vertex names
Using Igraph, I create shortest paths, then convert the matrix into
three column vectors - "vertex1", "vertex2", "shortestpath" - as the
code below shows.
#code for generating shortest path matrix and creating a 3 columns
from an igraph graph object "y"
y_s<-shortest.paths(y, weights = NULL)
y_s <- melt(y_s)[melt(upper.tri(y_s))$value,] #Step 2: this

Hi, David.
Spill intervals must be precolored because they can't be spilled once more.
They are the shortest intervals precisely over each def/use of the original
interval. That is why they also have their weights set to #INF.
Imagine that on a second iteration allocation algorithm figures out that
some spilled interval can't be assigned a physical register. Allocator can't
spill it

Problem with shortestPath in igraph and qgraph
hello,
I have a graph and i use qgraph package to calculate centrality parameters.
Now I want to know the maximum value of shortest path for each vertex with
discarding the Inf value in short pathes. For this I use the
ShortestPathLengths of centrality function in qgraph. but when I want to
get the maximum the result is wrong. here is my code:

Igraph library: How to calculate APSP (shortest path matrix) matrix for a subset list of nodes.
Dear R Users,
I have a network of 25000 total nodes and a list of 500 node which is a
subset of all nodes. Now I want to calculate the APSP (all pair shortest
path) matrix only for these 500 nodes.
I would appreciate any help.
Thanks in advance

Hard to follow data analysis without data. Try making your example reproducible [1][2][3] and post in plain text (a setting in your emailer). Read the Posting Guide mentioned in the footer to avoid other posting pitfalls.

Yes, that's true. But I wonder if we shouldn't be smarter about which
register we pick to color it.

An interesting call path observation..
This is not really a problem just something I noticed in my testing..
When two or more Asterisk servers are connected by IAX2 trunks it does
not make use of any "shortest path" type system.. (maybe this is still
planned somwhere down the line, but may come in handy to those who have
multi asterisk installations)
Here is the setup..

computing distance in miles or km between 2 street addresses
Hi R-ers:
I need to compute the distance between 2 street addresses in either km
or miles. I do not care if the distance is a "shortest driving route" or
if it is "as the crow flies."
Does anybody know how to do this? Can it be done in R? I have thousands
of addresses, so I think that Mapquest is out of the question!

CCA - manual selection
Hello,
I am trying to obtain f-values for response (independent) variables from a
CCA performed in vegan package, to see which ones of them have
significative influence in my dependent variables (like the manual selection
in canoco), but I can't find any function (or package) that do such a thing.
The dependents variables are species data, and the independents are
ambiental data.
Than you.

Migration, BigInts, and string lengths
Howdy Y''all,
I was thrilled to recently discover migrations, as that framework
addresses a common problem in an elegant way. I have, however, gotten
tripped up a bit as I''ve worked with them.
The first problem I encountered was that, though I was using a BigInt
data type in a field in my dev database, my unit tests were failing
because when I copied the schema from the dev

I have a problem with R!!
Dear all
i?m working with a program i?ve made in R (using functions that others
created)
to run my program i need a sample. if i generate the sample using for
example, rnorm(n, mu, sigma) i have no problem
but if i obtain a sample from a column in excel and i copy it, the program
says that there is a mistake: it says "Error en `[.data.frame`(data,
indices) : undefined columns
