Fwd: Documenting data sets with many variables
Hi,
since nobody answered to my first message, I try to explain my problem more
clearly and more general this time:
I have a data set in my R package "micEcon", which has many variables (82).
Therefore, I would like to avoid to describe all variables in the "\format"
section of the documentation (.Rd file). However, doing this lets "R CMD
check" complain about

Help with NaN when 0 divided by 0
Hi All,
I have some data where I am doing fairly simple calculations, nothing more
than adding, subtracting, multiplying and dividing.
I’m running into a problem when I divide one variable by another and when
they’re both 0 I get NaN. I realize that if you divide a non-zero by 0 then
you get Inf, which is, of course, correct. But in my case I never get Inf,
just NaN because of the structure

Double hurdle model in R
I am interested in utilizing this so called "double hurdle" model
in my study. We can write the model in the following way:
if (z'a + u > 0 & x'b + e > 0) y = x'b + e, else y = 0
In the model, consumption y is the (left-) censored dependent variable. e
and u are the normally distributed error terms. z'a is the participation
equation and x'b is the

conditional weighted quintiles
Dear All,
I am economist and working on poverty / income inequality. I need descriptive
statitics like the ratio of education expentitures between different income
quintiles where each household has a different weight. After a bit of
google search I found 'Hmisc' and 'quantreg' libraries for weighted quantiles.
The problem is that these packages give me only weighted quintiles;

libvirtd using 11GB
Hi All,
Am new to this list, and have asked in #ovirt / ovirt-users list and they
pointed me to here ... I've seen libvirtd using ~11 GB of resident memory
after the host has been running for about 60+ days with about 40 VMs
running on it.
The versions I'm currently running are :
libvirt.x86_64 0.9.10-21.el6_3.7

Netraverse Win4Lin in trouble or out of busienss?
Does anybody know what is happening with Netraverse the company who
makes Win4Lin? They appear to have closed down, their offices are shut
down and phones disconnected. Their internal user newsgroup is saying
most of their developers have been fired.
Their Web site (www.netraverse.com) looks like business for ususal. I
wonder what happens if you try to buy anything from them - I'll let

dev.print in R 1.7.1
Dear R experts
How do I save a plot to a file in a specified format, f.ex ’png’?
Apparently ’save.plot’ no longer exists, so I tried instead
dev.print(file="H:\\jesperf\\data1image",device=png())
However no file is created and – much worse – no graphics is produced
(on screen or file) if I run
f.ex qqnorm afterwards.
What am I doing wrong and how do I get R to print

How to retrieve a vector of a data.frame's variable attributes?
Hi,
I have a data.frame with 100 variables and I have assigned a "label",
"units" and "category" attribute to each variable. I would like to reorder
the variables in the data.frame by the "category" attributes but can't find
a way.
For example, the first variable is:
> attributes(hh$aez)

Complex Surveys...Specifying Design
I need some guidance from someone who is familiar/has some experience with

The data that I am using is from the Medical Expenditure Panel Survey

variables are varstr01 and varpsu01 respectively. When I try to specify

All mail in mbox disappears when using Outlook
I thought I was imaging it but... I have a friend (honestly) that likes to
clear his inbox every month by copying older into a folder (e.g. June-2009).
Every month he complains that all the mail in the new folder has
disappeared. This has happened three times now, and he's sort-of-right. I
now believe it's a bug rather than him.
The setup is Dovecot 1.1.3 on FreeBSD 7.0 and the client is
