Full_Name: Russell V. Lenth Version: 2.3.1 OS: Windows XP Pro Submission from: (NULL) (128.255.132.188) I wrote a simple .BAT file to run the Sweave function on a file (via RTerm), then run pdflatex on...

Dear package developers: I have run into a dilemma... I received a message that my package has errors on the development version of R; and that I must fix the error by August 26. Since I will be traveling out...

Do this: a <- c(0, 1, -1) V <- vcov(fit) sqrt(t(a) %*% V %*% a) Russ -----Original Message----- Message: 2 Date: Wed, 28 Oct 2020 21:29:53 -0500 From: Simon Harmel <sim.harmel at gmail.com> To: r-sig...

Package developers, I am acquainted with one of the authors of an interesting article on how software developers respond to, and manage, evolutionary changes in various multi-developer computing "ecosystems". The article has some preliminary results based on interviews with...

Maybe I can help. But what's the situation? Do you already have pilot data analyzed with one of those packages? If so, you can use that analysis to estimate the variance component nets needed for the sample-size calculation...

Thanks, Bert. This looks potentially useful as an alternative to the way I currently dynamically register the method. It does seem to require that 'pkg' must actually be installed on the system in order to work, and that pkg would...

The reviewers were NOT correct in questioning whether you had sufficient power. Power is the probability of rejecting a null hypothesis. You have the data, you did your analysis, so you know which hypotheses were rejected (retrospectively, the power of...

> There can't really be an "ImportGenerics", because S3 is so informal. A generic function is a function that calls UseMethod, but it can do anything else as well. So R would need some fancy code analysis to know whether...

Testing results for Bert's suggestion... I tested this with a different -- much smaller -- package: Put the S3method() construct in NAMESPACE but the generic package is not mentioned at all in any DESCRIPTION field. I built the package and checked...

... "I am not fixing this hot mess"??? To the contrary, the README contains a clearly expressed intention to maintain plyr to keep in on CRAN. RL -----Original Message----- From: Jeff Newmiller <jdnewmil at dcn.davis.ca.us> Sent: Tuesday, September...

All, How does one tell what version of pandoc is being used by winbuilder (and probably other related CRAN-submission processes)? I have a package with several HTML vignettes, for which I use a custom style. I had decided to...

Developers: Lately (the past month or so), I have been getting a ton of messages like the following whenever I rebuild my package: Rd warning: H:/progs/R/devel/EMMEANS/emmeans/man/xtable.emmGrid.Rd:57: missing file link 'print...

Dear R-Devel, As I am sure many of you know, a special issue of The American Statistician just came out, and its theme is the [mis]use of P values and the many common ways in which they are...

Hadley, As I suspected, and a good point. But please note that the term "retired" causes angst, and it may be good to change that to "superceded" or something else. As a side note, I'll mention that I myself...

Hello package developers, I just upgraded to R version 4.1.0, and now get a new error when I re-build my package. Among the messages about converting help files, I now get: ... update.emmGrid html REDIRECT:topic levels...

Developers, I have a package that has a number of vignettes with examples and such; so I see an increasing need to provide easier ways to navigate among them and to find a particular topic. All the vignettes are written...

Thanks, Duncan. That's helpful. In addition, I confess I had a closing parenthesis in the wrong place. Should be: . . . .GlobalEnv), silent = TRUE) Cheers, Russ -----Original Message----- From: Duncan Murdoch <murdoch.duncan at gmail.com> Sent: Saturday, August 10, 2019...

My package 'lsmeans' is now suddenly broken because of a new provision in the 'tibble' package (loaded by 'dplyr' 0.5.0), whereby the "[[" and "$" methods for 'tbl_df' objects - as documented - throw an error if a variable is not...

This is a question only about terminology. Suppose I have data categorized by three factors A, B, and C, with cell means ybar_ijk and cell frequencies n_ijk, where I, j, and k index A, B, and C respectively...

Dear all, I received an email from a user telling me that another package that depends on my package is licensed GPL(>=3), whereas mine is licensed GPL-2; and that therefore, the other package is in violation of its...
