how to fill out the empty spots when using rbind or cbind?
I have uneven vectors I want to use cbind or rbind to combine them into a matrix. Is there a way to make it so that R would not return error msg saying they're uneven?
Thanks.

Speeding up simulation of mean nearest neighbor distances
I've written the function below to simulate the mean 1st through nth
nearest neighbor distances for a random spatial pattern using the
functions nndist() and runifpoint() from spatsat. It works, but runs
relatively slowly - would appreciate suggestions on how to speed up
this function. Thanks. --Dale

Averaging uneven measurements by time with uneven numbers of measurements
I have a new device that takes measurements anywhere from every second, to
every 15 minutes (depending on changes). The matrix has a date, time and Y
column (Y is the measurement). For three days it is 25,000 rows. How do I
average the measurements by every 30 minutes so my matrix is 48 rows per
day? I have been working on this and cannot figure out a simple method. Any
ideas? Thank you.

String manipulation, insert delim
Hello All,
I've been using R for two years now and I am happy to say this is the
first time I could not find the answer to my problem in the R-help
archives. Here is the pending problem:
I want to be able to insert delimiters, say commas, into a string of
characters at uneven intervals such that:
foo<-c("haveaniceday")#my string of character
bar<-c(4,1,4,3) # my vector of

Using image/contour with unevenly spaced data...
Is it possible to plot unevenly spaced data with image/contour function?
Below is an example of the type uneven data that I'm trying to plot with
image/contour functions. For example, I would like to have the x-distance on
the x-axis and y-distance on the y-axis and then the temperature values
determine the color used. Unfortunately this data was sampled such that it is
not evenly

[Puppet Upgrade] Puppet agent does not work
I upgraded Puppet master from 2.7.6 to 2.7.20 on CentOS5.8_x86_64.
But when I tried to launch ''puppet agent -t'' on one of staging servers, the
puppet daemon did not work and got heaps errors.
I have no idea what made it wrong and how to fix it.

uneven vector length issue with read.zoo?
I truncated and simplified my code and the read in data that I'm working with

plot, y-axis, uneven scale???
Hello,
I have a question about the y-axis of plots. Actually I had about 60
values. About 80 percent of these values are less than 0.2, then the other
20 percent values are more than 4,max is 10. So when I plot these values
together, the y-axis's range will go 0 to 10, and my major values (80%
values <0.2) will be pressed around 0 on the bottom, while other several
dots will scatter in

[PATCH] btrfs-progs: No-op when called as fsck.btrfsck
Hi,
I thought that I would attempt a quick little patch that will make btrfsck into
a No-op when called as fsck.btrfsck.
The reasoning is that the FAQ states that it is recommended and safe to do so,
and the current 12.04 version of Ubuntu just symlinks fsck.btrfsck to btrfsck
instead of /bin/true.
PS - Apologies if I mess this git send-email up!

where''d we come from?
I''m curious -- how many of us came to Rails from other branches of the OO
world -- Java, C# -- and how many of us came from the design or non-OO
scripting worlds?
Reason I ask is that I''m finding Rails a blast and very productive, but I
think one reason is that I already cut my teeth on MVC and ORM during two
years of writing apps with J2EE/Struts/Hibernate. And in Javaland, it

Drawing asymmetric error bars

I have data which I have arcsin transformed to analyse.
I want to plot my data with error bars however as my data is
back-transformed my standard errors are uneven.
Is there a simple way to draw these asymmetric error bars in R?
Thanks for your help.

create an object from a string?
I''m trying to dynamically create an instance of an object at runtime, from a
String. I have a method that returns one of a number of Strings ("Car",
"Motorcycle", "Bicycle"), and when I receive the String, I then want to
instantiate one of those objects.
Seems like there should be a way to do it in Ruby, but maybe I''ve been up

Splitting a set of vectors in a list
I have a set of character vectors of uneven length
that I have stored in a list. I can easily enough get
any column of them using lapply but what I want is to
be able to create a matrix of them. Other than some
kind of brute force looping approach I have drawn a

Would somebody please suggest something? Thanks

nuby: do models have to inherit directly from ActiveRecord?
Hello,
I have a few models -- book, cd, dvd -- for which I''d like to have an
abstract base superclass to hold some common stuff. That abstract class, I
was thinking, would inherit from ActiveRecord.
Didn''t work, though, and looking around, I found this:

simple, unidimensional heat map
I was wondering if someone could point in the direction of a package
that could generate not heatmaps, but something like a unidimensional
heat map.
I might be mistaken, but it seems like image and heatmap are an
overkill for such a simple task.
For example, if I have a data frame:
x<-data.frame(myname=paste("value",1:10,sep=""),a=1:10,b=sample(1:10,10,replace=T))

javascript in link_to?
having trouble finding how to include a random chunk of javascript (an
onclick event handler) in a link_to generated link.
at first i thought i could use the html_options field, but if i understand
correctly, that only supports :confirm, :popup, and :post options.
hope i''m wrong. anyone know different?

New Rails Site: Wordie
My latest stupid web trick, built, with love, in Rails:

Make lists of words. See who else likes the same words. Basically, it''s
a dating site. Built on thanksgiving while half-watching football and
