Hello All, Has anyone written a function for the distribution function of a *doubly* non-central F-distribution? I looked through the archives, but didn't find anything. Thanks! Wolfgang

See ?par and its "mar" argument. > Could you tell me also how to change the size of the chart? There is not > enough space below the chart to add the arrows!

Dear All, I know that for package nlme, lmeObject$apVar contains an approximate covariance matrix for the variance-covariance coefficients. Do "mer" objects created by lmer contain something analogous? Thanks in advance for any pointers! Best, Wolfgang

Hi All, It seems to me that xyTable() gets thrown off by NAs: x <- c(1, 1, 2, 2, 2, 3) y <- c(1, 2, 1, 3, NA, 3) table(x, y, useNA="always") xyTable(x, y) Is this intended...

Hello, I am using Ubuntu 16.04, using the default (Unity) window manager. The font size using View() is way too small on a high dpi monitor. I already use scaling, but View() doesn't seem affected by that. Any...

Dear All, I looked at help(par), but could not figure out which setting controls the distance between the x-axis values and the x-axis title. Any pointer would be appreciated! Thanks in advance, -- Wolfgang Viechtbauer ?Department of Methodology...

Hi All, I asked this over at r-help, but didn't get any responses. As this seems like a bug (or at least undocumented behavior) to me, I'll try again here. It seems to me that xyTable() gets...

Dear All, help(influence.measures) shows that there are generic functions for dfbetas(), covratio(), cooks.distance(), hatvalues(), and a few others, but apparently not for dffits(). Wouldn't it be more consistent to have a generic function for this in...

A new package is now available via CRAN, called metafor. The metafor package consists of a collection of functions for conducting meta-analyses in R. Fixed- and random-effects models (with and without moderators) can be fitted via the general...

Dear lme4 Authors, I am wondering if a lme4.0 version (i.e., a backwards compatible, bug fixes only version) is still going to be released (via CRAN). I noticed that lme4 version 1.0-4 is (currently) available for...

Indeed, rmat() is based on Olkin & Finn (1990), so you could just say that the covariances were computed based on the equations in that article. Best, Wolfgang -----Original Message----- From: Mark White [mailto:markhwhiteii at gmail.com] Sent: Thursday, 18...

For those who missed the useR2017 conference (like me) -- most (all?) talks/presentations are available online: https://channel9.msdn.com/Events/useR-international-R-User-conferences/useR-International-R-User-2017-Conference These are the meta-analysis related talks I...

Hello, I am using Ubuntu 16.04, using the default (Unity) window manager. The font size using View() is way too small on a high dpi monitor. I already use scaling, but View() doesn't seem affected by that. On...

Try: regression <- lm (biomass ~ poly (temperature, degree=2, raw=TRUE)) See the help page for poly what raw=TRUE does. Best, -- Wolfgang Viechtbauer ?Department of Methodology and Statistics ?University of Maastricht, The Netherlands ?http://www.wvbauer.com/ ----Original Message---- From...

The 'meta' and 'metafor' packages provide this. See also the meta-analysis task view: https://cran.r-project.org/web/views/MetaAnalysis.html (especially: "Investigating small study bias"). Best, Wolfgang -- Wolfgang Viechtbauer, Ph.D., Statistician | Department of Psychiatry and Neuropsychology...

Dear Mario, See: http://www.mail-archive.com/r-help at r-project.org/msg117622.html This seems to be fixed in version 2.12.1 (at least, I do not get this problem anymore). Best, Wolfgang ________________________________________ From: r-help...

Dear All, I just submitted a new version (1.9-8) of the metafor package to CRAN. The checks show an error for r-release-osx-x86_64-mavericks: https://cran.r-project.org/web/checks/check_results_metafor.html...

Suppose I have a function funcA() in package pkgA that requires function funcB() from another package pkgB under certain circumstances. Those circumstances are rare though, so I put package pkgB under 'Suggests', and use this in funcA() when those circumstances...

I was not sure who I should contact about this, so I am posting this here. There are a few broken links on the R website. 1) http://www.r-project.org/search.html -> link to the Nabble R Forum...
