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...

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 C...

Here is what I see in the current version: .libPaths(), the library trees where R looks for packages gives: [1] "G:/uitapps/HEBB_R_LIB2/library" [2] "C:/Program Files/R/R/R-3.1.1/library" If I try to install a new package, e.g., install.packages("rockchalk") I get "G:/uitapps/HEBB_R_LIB2/library is not writeable. Use a personal library instead?", followed by a popup window, "Create ~R/library? (y/n)" This then installs the package, but to "C:/Users/friendly/Desktop/~R/library". In the current login se...

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 the test verion, which is now at 1.7.I'm lea...

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.

....freefaculty.org/R/Rchaeology.pdf and tell me if you think it is wrong headed, and 2. Supposing you do not think I'm completely wrong, would you care to point me at more examples of R idioms that lead to deep insights into the nature of R programming? Longer more boring explanation: In the rockchalk package, I have functions to make it easier to teach regression to students who aren't R programmers. I just uploaded package version 1.6 to CRAN. While I do this, I'm reading R source code all the time because I need to understand how functions like summary and anova receive R objects, tak...

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 f...

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 concentrated on that problem. Fitting regressions is pretty easy, but getting predicted values for particular combinations of input values can be difficult when the model is complicated. If you agree, pl...

To extwnd on Martin 's explanation : In factor(), levels are the unique input values and labels the unique output values. So the function levels() actually displays the labels.

I'm the faculty member in my department who advises our IT staff on the details of installing R for students and faculty on our Windows 7 lab network. We are about to upgrade from R 3.1.1 to R 3.2.1, and once that is done, this version of R and all installed packages will be frozen in the image that appears in C:/Program Files/R/R-3.2.1/ on every lab computer, and this image is refreshed

...e names outside the edges like this par(xpd=T) text(datsummNT$mean, datsummNT$var, labels=rownames(datsummNT), cex=0.8) ## but that is not much better par(xpd=F) ## Here is one fix. Make the unused space inside the plot larger by ## making xlim and ylim bigger. I use the magRange function from ## rockchalk to easily expand range to 1.2 times its current size. ## otherwise, long variable names do not fit inside plot. magRange ## could be asymmetric if we want, but this use is symmetric. library(rockchalk) rownames(datsummNT) rownames(datsummNT) <- c("boring var","var with long name&...

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. http://pj.freefaculty.org/guides...

...evels = c("Male", "Man", "male", "Female")) levels(xf) <- c("Male", "Male", "Male", "Female") I think it is quirky that `levels<-.factor` allows the duplicated labels, whereas factor does not. I wrote a function rockchalk::combineLevels to simplify combining levels, but most of the students here like plyr::mapvalues to do it. The use of levels() can be tricky because one must enumerate all values, not just the ones being changed. But I do understand Martin's point. Its been this way 25 years, it won't chang...
