Greetings I want to take a fitted regression and replace all uses of a variable in a formula. For example, I'd like to take m1 <- lm(y ~ x1, data=dat) and replace x1 with something else, say x1c, so the formula would become m1 <- lm(y ~ x1c, data=dat) I have working code to finish that part of the problem, but it fails when the formula is more complicated. If the formula has log(x1)

Here's my little discussion example for a quadratic regression: http://pj.freefaculty.org/R/WorkingExamples/regression-quadratic-1.R Students press me to know the benefits of poly() over the more obvious regression formulas. I think I understand the theory on why poly() should be more numerically stable, but I'm having trouble writing down an example that proves the benefit of this. I

Yesterday I uploaded new rockchalk_1.8.97. Then I received email saying that I needed to confirm the submission. Here's the message. Dear Paul E. Johnson Someone has submitted the package rockchalk to CRAN. You are receiving this email to confirm the submission as the maintainer of this package. To confirm the submission to CRAN, follow or copy & paste the following link into your

Greetings. I'm teaching linear regression this semester and that means I write more functions for my regression support package "rockchalk". I'm at a point now were some fresh eyes would help, so if you are a student in a course on regression, please consider looking over my package overview document here: http://pj.freefaculty.org/R/rockchalk.pdf That tells how you can grab

Quite possibly, I should keep my big mouth shut and let the CRAN'ers answer this, but at face value, you submit a new version and are asked to confirm that problems with the previous version are fixed; isn't that as it should be? -pd On 08 Feb 2016, at 16:10 , Paul Johnson <pauljohn32 at gmail.com> wrote: > Yesterday I uploaded new rockchalk_1.8.97.

I mistakenly left a write in "/tmp" in the rockchalk package (version 1.8.109) that I uploaded last Friday. Kurt H wrote and asked me to fix today. While uploading a new one, I became aware of a problem I had not seen. The version I uploaded last Friday, 1.8.109, has OK status on all platforms except r-release-windows-ix86+x86_64. I get OK on oldrel-windows and also on devel-windows.

I set up a local repo for testing packages. My packages are not showing up from the repository when viewed by Linux clients. I suspect this is a web administrator/firewall issue, but it could be I created the repo wrongly. I am supposed to run write_PACKAGES separately in each R-version folder. Right? Maybe other novices can use these scripts, if they are not wrong :) Here's the file

Greetings: rockchalk is a collection of functions to facilitate presentation of regression models. It includes some functions that I have been circulating for quite some time (such as "outreg") as well as several others. The main aim is to allow people who do not understand very much R to survive a course in intermediate regression analysis. The examples included with the functions

I have been making simple functions to display regressions in a new package called "rockchalk". For 3d illustrations, my functions use persp, and I've grown to like working with it. As an example of the kind of things I like to do, you might consult my lecture on multicollinearity, which is by far the most detailed illustration I've prepared.

In the rockchalk package, I want to provide functions for regression objects that are "well behaved." If an object responds to the methods that lm or glm objects can handle, like coef(), nobs(), and summary(), I want to be able to handle the same thing. It is more difficult than expected to ask a given fitted model object "do you respond to these functions: coef(), nobs(),

I suppose everybody who makes a package for the first time thinks "I can change anything!" and then runs into this same question. Has anybody written out information on how a package can override functions in R base in the R 2.14 (mandatory NAMESPACE era)? Suppose I want to alphabetize variables in a summary.data.frame, or return the standard deviation with the mean in summary output.

Hi I have multi domain environment with root domain and subdomain. Forest and domain level windows 2003 native. Also forest prep and domain prep did for sccm 2007 ocs 2007 and Exchange 2003. After join Samba to domain like ad dc I had some problem with replication: ################################################# [root at dc03 ~]# samba-tool drs replicate dc02 dc03

I'm pasting below a working R file featuring a function I'd like to polish up. I'm teaching regression this semester and every time I come to something that is very difficult to explain in class, I try to simplify it by writing an R function (eventually into my package "rockchalk"). Students have a difficult time with predict and newdata objects, so right now I'm
