[Env: Win XP, R 2.14.2, R 2.15.0] I have a replacement function for setwd() in my .Rprofile which displays the current R path in the R window title. It no longer works in R 2.15.x, giving the error below. Worse, the error prevents the rest of my .Rprofile script from completing. Is there some way to rescue this, i.e., preserve this behavior in R 2.15? If not, how can I modify my script so it

[Environment: Win XP, R 2.10.1] In my Rprofile I have startup code to do various things, intended for when I use the Rgui console. Some of these are causing problems in JGR now that I've installed it. How can I test for R running with Rgui to do some of these things only there? -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. York University

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

In my .Rprofile for Windows, I had the following functions defined to mirror a few features I miss from linux: (a) replace setwd() with a version that stashes the current directory so it can be easily restored (b) writes a short version of the current R directory to the Windows title bar: I can always see where I am, with multiple Rgui windows. (c) creates a cd() shorthand for setwd(), but

Let's say I have a package that consists of a set of functions, fig1(), fig2(), fig3() ..., each of which produces a plot, and perhaps some printed output, e.g., fig1 <- function() plot(1:10) fig2 <- function() plot(10:1) fig3 <- function() {y<-sample(1:10,10); plot(y); y} I'd like to produce a document (PDF or HTML) containing the listing of each function and its output,

the NEWS file for R-devel says * Even data-only packages without *R* code need a namespace and so may need to be installed under *R* 2.14.0 or later. but what should this contain? Can it simply be an empty NAMESPACE file? I assume that data does not have to be exported. -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept. York University

Have you looked into your .Rprofile file? Loading packages is not something R normally does without your telling it to do so, but many people forget that they have done so.

[env: Windows, R 3.6.6] When I start R from the R Gui icon or from RStudio, I get a large number of packages loaded via a namespace. Not entirely clear where these come from. As a result, I often run into problems updating packages because something is already loaded.

[Env: WinXp, R 2.9.2] In my .Rprofile, I define a number of utility functions I'd like to have available in my R session, but don't want them to be *normally* listed by ls(), or more importantly, saved if I save my session variables/functions.

I'm looking for an R equivalent of Beaton's (1964) Sweep algorithim for partial inversion of a matrix by pivoting.

Under Windows (and maybe others) you can use file.choose() as a substitute for an explicit file= argument in most places. Is there an analog for what I'll call dir.choose(), so that I can say setwd(dir.choose()) thx, -Michael -- Michael Friendly Email: friendly AT yorku DOT ca Professor, Psychology Dept.

A simple question, but I can't find something to do what I want: Given: a vector of numbers, like lambda <- c(0, 0.005, 0.01, 0.02, 0.04, 0.08) Desired: format them in minimal space for use as plot labels, ie, without leading or tailing 0s. For this example: lambdaf <- c("0", .005", ".01", ".02", ".04", ".08") -- Michael

Using R 2.13.1, I am now getting the following NOTE when I run R CMD check on my HistData package * checking for unstated dependencies in examples ... NOTE 'library' or 'require' calls not declared from: gplots sp Under R 2.12.x, I didn't get these notes. I have ~ 25 .Rd files in this package, and AFAICS, every example uses library or require for the functions used;

Can you be more specific about what conditions cause R to automatically load a package when a .RData file is loaded? My experience has actually been the opposite.

In a long session, producing multiple graphs, I sometimes repeatedly change par() settings, particularly with multi-row/col displays. If I'm using a script, I'll do op <- par(newsettings) ... plots ... par(op) but sometimes I do things on the fly and can't easily back out to the default settings. I'm looking for someway to do the equivalent of par(reset=TRUE) I suppose I

A minor gripe/request: Could all R CMD package tools not at the very least be consistent in indicating when they are done, as in * DONE (packagename) or at least * DONE R CMD build leaves one hanging, not knowing whether it has completed or it is time to get another coffee. * checking for file 'C:/Documents/workspace/heplots/DESCRIPTION' ...

It is A Good Thing to regularize Authors and Maintainers of packages, particularly for citation() and toBibTex().

I want to use something like printCoefmat() in a print.summary method to print a more nicely formatted version of the result from a summary method, but where the estimates may be cross-classified by one or more factors. However, printCoefmat() assumes that the labels for the parameters are the rownames of the object, and prints factors as integers. With one factor, I could just assign that as
