There will be a meeting of the Ottawa Gatineau R Users Group on Monday November 10 from 4pm to 6pm. More details are provided below. Please pass this message along to friends you think may be interested. Paul Gilbert _________ Dear R friends: To get OGRUG going again I've reserved room DMS 6160 in the Desmarais Building of the University of Ottawa for 1600-1800 November 10. This is the

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on

I have been talking with Gabriel Wainer about the possibility of some community building with R and simulation workers. The conference announced below is just before UseR (but in that capital to the north of Washington). If anyone on this list is participating or thinking of participating, perhaps they could let me know off-list. Ottawa-Gatineau R User Group would likely try to set up some

There are now several R geographic user groups, and a few have mailing lists on the R mailing list system. Thanks to Martin M, there's also a pointer to a page I'm maintaining to list/describe the groups. The page is at http://macnash.telfer.uottawa.ca/RUG.html Contact me if you have a listing. I'm prepared to wikify it if there is sufficient interest. John Nash

Hi all, I have a (hopefully quick) question. I've got a fascinating set of fitted surfaces in three dimensions corresponding to local linear multiple regressions. I'd like to add rugs to the X and Y axes (corresponding to my independent variables) in order to get a sense for how many data points I'm working with to graph various portions of the surfaces. The trouble is, I can't

predict.warn() -- a function to display factor levels in new data for linear model prediction that do not exist in the estimating data. Date: 2005-8-24 From: John C. Nash (with thanks to Uwe Ligges for suggestions) nashjc at uottawa.ca Motivation: In computing predictions from a linear model using factors, it is possible to introduce new factor levels. This was encountered on a practical

I appear to have hit one of the "drop" issues raised in some discussions a couple of years ago by Frank Harrell. They don't seem to have been fixed, and I'm under some pressure to get a quick solution for a forecasting task I'm doing. I have been modelling some retail sales data, and the days just after Thanksgiving (US version!) are important. So I created some dummy

Hi! (a complete newby, but will not give up easily!) I was wondering if there is any way to decouple the axis and tick mark widths? As I understand they are both controlled by the lwd setting, and cannot be controlled independently? For example I might want to create major and minor ticks, which I now know how to do by superimposing two axes with different at settings, but what if I also wanted

Hi all, I need to run several simple linear regressions at once, using the following data. Response variables: Bird species (sp 1, sp2, sp3...spn). Independent variable: Natprop - proportion of natural area. covarate: Effort = hours). One single linear regression would be: lmSp1 <- lm(sp1~ natprop + effort). However, I need to run this linear regression for all bird species that I have

Hi I could only find some discussion on this wrt lattice graphics (which I'm not using). Apologies if I'm missing something obvious. I'd like to produce 3 rug plots under a kernel density plot for a population. The population is subdivided into 3 subpopulations, which I'd like the rug plots to highlight. Naturally, when I do 3 rug plots, they all plot over each other.

Hello dear R community, Recently, the wonderful people<http://www.warwick.ac.uk/statsdept/useR-2011/index.html#About>behind useR!2011 made sure to nudge the speakers to send in their slides from the conference, and updated the conference's website with links to the slides (and videos)<http://www.warwick.ac.uk/statsdept/user-2011/schedule/index.html>of the talks.

Hi, My name is Jun Mao and I am a graduate student at University of Ottawa. My research topic is multivariate quality control. I did my simulation in R. My supervisor and me develop a new nonparametric cusum method. We want to edit as a R package and submit it as standard package to R. Can you tell me how is the procedure?

Hi all! I've written a handy script that uses a for loop to allow me to generate a large number of figures and statistical outputs for a large dataset. I am using indexing to retrieve a species name for the title of my graphs- which worked fine. However, I need to italicize these species names. I originally used the paste function, and had no problems with indexing: *main=paste("Yield

The message below came to me from the Getting Open Source Logic INto Government list. I'm passing it on to the devel list as the infoworld article may have some ideas of relevance to the R project, mainly concerning build and test issues and tracking changes in the code base. While the LibreOffice project is very different from R, there may nevertheless be some tips we can borrow in the

Is there any automatic mechanism for extracting a likelihood or test statistic distribution (PDF or CDF) from an object of class "htest" or from another object of a general class encoding a hypothesis test result? I would like to have a function that takes "x", an object of class "htest", as its only argument and that returns the likelihood or test statistic

Hi all, I''ve been using Shorewall 1.42 for a month on two firewalls at work and my own personal colocated server and love it. While pretty familiar with iptables, I don''t like dealing with it on a daily basis, and Shorewall certainly makes life easier. I''ve deployed Shorewall on both our Toronto and Ottawa office firewalls, and have configured a FreeS/WAN IPSEC
