Hello All, I am wondering if there has ever been any discussion/consideration given to incorporating MathJax (or something similar) into R for rendering equations in .Rd files. I know that equations are rendered beautifully in the pdf manuals, but I suspect the majority of users primarily look at the html help files when using R. While I am comfortable reading something like "B_x(a,b) =

Hello all, I am using forest.rma to plot a random effects model meta-analysis. I noticed that refline sets a vertical line indicating the null hypothesis. Is there a way to draw another vertical line, possibly dashed, centered on the summary estimate? Prof. Viechtbauer, if you happen to read this, I'd like to thank you for making an excellent package. I have been using the metafor package to do my first meta-analysis, having never used R before. The documentation is thorough and intuitive. Thanks, John John Williams ALB Candidate Harvard University Extensi...

Hi, I have been looking for an R package which allowed to do meta-analysis (both pairwise and network/mixed-treatment) at arm-level rather than at trial-level, the latter being the common way in which meta-analysis is done. By arm-level meta-analysis I mean one that accounts for data provided at the level of the individual arms of each trial and that does not simply derive the difference between

In other words, I don't want to plot the "1" at every data point, but only at every kth point (things get too cluttered when there are many data points).

Dear All, The metafor package currently fails CRAN checks on Sparc Solaris: http://cran.r-project.org/web/checks/check_results_metafor.html The problem is probably due to an unintended (= stupid) use of identical() in a couple tests. I have changed that to more appropriate tests using all.equal(). However, before I resubmit the package to CRAN, I would really like to make sure that the updated

...on what you wrote, it seems as if these are non-randomized studies "with one or the other procedure applied." Therefore, any comparisons you make would be purely observational and may be related to other variable that confound any difference you may find.

Dear All, In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example: myfun <- function(y) { out <- list(y=y) class(out) <- "myclass" return(out) } print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5)) myfun(1:4) # prints: [1]

...,y)) List of 3 $ x : num [1:5] 1 2 2 5 6 $ y : num [1:5] 2 2 4 NA 3 $ number: int [1:5] 2 1 1 1 1 table() does not use this logic, as one NA in a vector would make all the counts NA. Should xyTable have a way to handle NAs the way table() does? -Bill On Tue, Apr 25, 2023 at 1:26?AM Viechtbauer, Wolfgang (NP) < wolfgang.viechtbauer at maastrichtuniversity.nl> wrote: > Hi all, > > Posted this many years ago ( > https://stat.ethz.ch/pipermail/r-devel/2017-December/075224.html), but > either this slipped under the radar or my feeble mind is unable to > understand wha...

Dear Wolfgang Viechtbauer and list members: I have discovered your "MiMa" function for fitting meta-analytic mixed-effects models through an earlier discussion on this list. I think it is extremely useful and fills an important gap. In particular, since it is programmed so transparently, it is easy to adapt it...
