Dear all, I've encountered a curious problem. I am trying to run an SQL query using sqlQuery() function in RODBC. The query works fine when run in a stand-alone SQL browser (Microsoft Query Analyzer, in particular). However, when I use the exact same thing from sqlQuery() function, I get the following error: Error in "[.data.frame"(data, , ) : not all specified columns exist

Hi, I would like to get lapply() to work in the natural way on a class I've defined. As far as I can tell, lapply() needs the class to be coercible to a list. Even after I define as.list() and as.vector(x, mode="list") methods, though, I still get an "Error in as.vector(x, "list") : cannot coerce to vector". What am I doing wrong? # dummy class

Dear all, I am just getting into R, and I arrive with a task in hand. I need to handle time series of price data, and use them in regressions and cluster models of various kinds. At this time, I am just trying to learn the most graceful ways of working with date-indexed data in R in general. I know of the ts object; however, it seems to assume a very regular periodicity of the data.

Dear all, Currently, a ts object behaves like an array, and it would be very useful to have a similar object, which would behave like a data.frame, i.e. it could be indexed, named, etc. like a data.frame. What would be the most efficient way to construct such an object? I have tried to make one on my own following the directions of class design from "S Programming" (2000) as a

Dear all, My colleague, who has been helping me with wrapping some older C++ code for use in R, has been running into some issues, which he asked me to post here: - ERROR is defined in RS.h which is included in Rdefines.h which conflicts with Visual Studio's ERROR - TRACE is defined in Rinternals.h which conflicts with Visual Studio's TRACE - math.h is included within extern

I'm trying to replicate a time-series cross-sectional analysis (countries over years) with SEs clustered by country. ?The original analysis was done in Stata 10 with: xtreg [DV] [IVs] fe cluster(country). Using plm() in R (cran.r-project.org/web/packages/plm/index.html), I've replicated the coefficients. I sought to estimate country-clustered SEs with vcovHC(), and tried a variety of

I wonder if there is a package that will estimate a Zero Inflated Poisson Model (ZIP), and also if there is a package that will estimate what is called the Tobit model: that is a combination of censored and observed values in the same sample.

Hello, I am trying to use augeas via puppet, augeas { "mailops": context => "/files/etc/sudoers", changes => [ "set spec[user = ''%mail-ops'']/user %mail-ops", "set spec[user = ''%mail-ops'']/host_group/host ALL", "set spec[user = ''%mail-ops'']/host_group/command[1] \"/bin/su

The following function is based on code I found here in an earlier thread. define sudoer() { augeas { "sudo${name}": context => "/files/etc/sudoers", changes => [ "set spec[last() + 1]/user ${name}", "set spec[last()]/host_group/host ALL", "set spec[last()]/host_group/command NOPASSWD: ALL", "set

Has anyone attempted to use the augeas type to add a service? I got the service to add no problem, but having some difficulties to get the match to work to prevent duplicate entries from adding. Since the service-name[*] has endless number of entries I used a glob so it checks all the entries but that does not seem to work. Any ideas on how to proceed? augeas { app_tcp'': context

Hi, I exposed few days ago this situation on the IRC, but unfortunately I haven''t found a way to solve it yet. I run the Puppet Master with multiple environments, and everything is working good but a couple of nodes that are causing me some troubles. These nodes are pointing to my production environment and I need to point them back to development to grab some changes I made. I

Hi all, I''m just starting to look at using Augeas with Puppet to manage some of our configuration files. I thought I would start with a simple task of removing an entry from the /etc/hosts file. I''m not finding it simple though! We have a number of hosts with entries in the /etc/hosts file like this: 127.0.1.1 hostname We would like to remove these lines. Now I know this can

I suspect this has more to do with Ruby than Puppet, but I know little about Ruby and Google has failed me, so I''m asking here. I''m finally getting some of our older systems brought into Puppet. I installed it on several this morning without incident, but there are two (more or less identical RHEL 5.3 systems) that throw horrible errors. These systems did not have Puppet or Ruby

New to mailing lists and Markup as well so please bear with me. I have been looking for two things. A project management system that syncs with Notational Velocity as well as something that lets me write and format script in plain text, then have that converted to the proper formatting for a script. I was wondering would Markdown have the ability to do this or have the changes necessary for this?

So, I’m using templates for the first time and I wanted to test the case where the values used by the template don’t exist. I get an error like this: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse template slapd_replication.erb: Could not find value for ''slapd_consumer_rid'' at /etc/puppet/manifests/experimental/services/ldap.pp:141

Hi, I need to add one line to /etc/securetty, say it needs to be ttyS1. Do not add it if ttyS1 already exists in file /etc/securetty. How to achieve this using puppet module in puppet 2.5? This file is different than the other examples using augeas, this one only has value per line, not name-val pair.

Hello, I would like to have the following line (among others) in my /etc/xinetd.d/rsync file : server_args = --daemon --address=<ipaddress_eth0> --log-file=/var/log/rsyncd.log To this end, i am using the camptocamp rsyncd module available from git.
