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

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

How about allowing underscore? (I believe WRE is silent on this, and I have not tried submitting a package with underscore in the title.) As I pointed out in my OP, _optim()_ works. And we have the advantage that we can distinguish package from function. The purpose of consistent editing is surely to provide the affordances that save us from needing extra documentation, as per Donald Norman's

After some thought, I decided r-devel was probably the best of the R lists for this item. Do feel free to share, as the purpose is to improve documentation and identify potential issues. John Nash The R Consortium has awarded some modest funding for "histoRicalg", a project to document and transfer knowledge of some older algorithms used by R and by other computational systems. These

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, I would also be in favor of a stronger stance on licenses. In industry, where we can really get in big trouble for violating a license, we often maintain internal repositories, or need to be careful about filtering what is used from CRAN. I think that is should really be a requirement the package authors commit to stating what the restrictions are on their packages. Nicholas On 10

Hi, While doing the ADF test in R using the following command I am getting the error and the result.."> x.ct=ur.df(rev$REVENUE,start=1,end=length(rev$REVENUE),frequency=1) Error in ur.df(rev$REVENUE, start = 1, end = length(rev$REVENUE), frequency = 1) : unused argument(s) (start = 1, end = 4, frequency = 1) >

Dear Wizards - Thank you so much for your help. That was exactly what I was looking for. Now, I have been working on conditional selection of columns in a data frame. My goal is to calculate the total revenue per sales representative per status in a table. I have come to a complete stop: Let's say, we have a data.frame called df with several columns and a number of rows: df <-

Hey everyone, I am currently creating a startup with a friend, and would love to tell you a little bit about it as we are actively seeking a Ruby on Rails developer to work with us. If you are interested in an entrepreneurial adventure, this could be a perfect opportunity. About Jolibook The publishing industry has evolved a lot over the past few years and self-publishing has become

Hendrik pointed out it was the parentheses that gave the complaint. Single quotes and no parentheses seem to satisfy R CMD check. Perhaps that needs to be in the WRE. However, I have for some time used the parentheses to distinguish functions from packages. optim() is a function, optimx a package. Is this something CRAN should be thinking about? I would argue greater benefit to users than title

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.

Hi there, Does anyone have Dovecot working correctly with pam_mkhomedir, please? I seem to be going through quite a number of IMAP servers this week, trying to find one that will not only authenticate against a Windows domain but which will also create home directories for users the first time they log in. I'm using winbind to do the authentication & that seems to be doing the trick

Dear R Helpers, I have a list that contains a number of objects, each of them financial statement data from quantmod (although I don't think that knowledge of quantmod is necessary to help with this problem). > str(listfinobj) chr [1:4815] "A.f" "AA.f" "AACC.f" "AAME.f" "AAN.f" "AAON.f" "AAP.f" "AAPL.f"

I'm planning to try to use Mike Powell's new BOBYQA optimization routine to see if it is a good candidate to eventually replace Nelder-Mead as the optim() default. (Don't panic -- this won't happen quickly.) Mike writes f77 code. After some chasing about, I've realized that because optimization codes need to call the objective function written in R, they need to use a language

The following example gives output with a line length of 103 on my system. It is causing a nuisance in creating a vignette. Is there something other than e.g., options(width=60) I need to set? The Sweave FAQ suggests this should work. options(width=60) pastured <- data.frame( time=c(9, 14, 21, 28, 42, 57, 63, 70, 79), yield= c(8.93, 10.8, 18.59, 22.33, 39.35, 56.11, 61.73, 64.62,
