Hi All, After some tinkering, and with support from Duncan, I put together a package that allows for easy inclusion of MathJax equations in Rd files. The package has been submitted to CRAN, but those who want to try this out already can get it here: https://github.com/wviechtb/mathjaxr or in other words: install.packages("remotes")

Thanks Gabor and Duncan! It works. For those interested, I added this to the beginning of the \details{} section: \if{html}{\out{ <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax at 3/es5/tex-mml-chtml.js"> </script> }} And then I can use: \if{html}{\out{\(B_{x(a,b)} = \int_0^x t^{a-1} (1-t)^{b-1} dt\)}} or

Hi All, I am compiling R-devel on Linux (Ubuntu 16.04.2) and that works just fine, but I am missing some of the expected features, as shown here: https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Linux In particular, after configure (using all defaults), I see: R is now configured for x86_64-pc-linux-gnu [...] Interfaces supported: X11 External libraries:

Dear R-Helpers, I have a large data matrix, which contains missing data. The matrix looks something like this: 1) X X X X X X NA NA NA 2) NA NA NA NA X X X X X 3) NA NA X X X X NA NA NA 4) X X X X X X X X X 5) X X NA NA X NA NA NA NA and so on. Notice that the first row starts with complete data but ends with missing. The second row starts with missing, but the rest is

Interesting. I gave this a try, but couldn't make this work. One would have to infuse something like <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax at 3/es5/tex-mml-chtml.js"> </script> or <script id="MathJax-script" async src="<url-to-your-site>/mathjax/tex-chtml.js"> </script> into

Hello Everybody, Is there a function available for calculating the density of a non-central t distribution? (dt does not accept the ncp option).

Yes. Thank you; I should have quoted it. I suggest to remove this text or to add the word "not" at the beginning.

Dear All, I am working on a function that has an optional data argument, just like lm(). If the user sets the data argument equal to some dataframe, then the function should look inside the dataframe for the variables given to other arguments, otherwise the variables should be accessible from what I believe is called the parent frame from which the function was called. I looked at the source code

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. I belive the correct/new URL should be: http://r.789695.n4.nabble.com/ 2) http://www.r-project.org/other-docs.html -> link to "Auswertung ?kologischer Daten". Not sure if there is a new

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

Hello, outer() is great for avoiding things like: for (val1 in val1s) { for (val2 in val2s)) { x[i,j] <- somefunction(val1, val2) } } The same can be obtained with: outer(val1s, val2s, somefunction) But what if there are three (or more) sets of values to loop over? Any way of avoiding the loops then? Thanks, -- Wolfgang Viechtbauer

Dear Dushanthi, Please keep your e-mails on the R-Help list, where Michael has already given you some excellent advice. As Michael already explained, metafor can handle proportions, but does not have any specific functionality for categorical variables with more than 2 levels (at the moment). So, if it is logical and possible to do so, you could collapse the levels of the categorical outcome to 2

Hello R-Helpers, plot(x, y, type="b", pch="1") plots x vs. y with both a line and the symbol "1" but how do I change the "spacing" of the symbol being plotted. 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). Thanks in advance! --

At least one, the third entry, but the fourth entry, (2,NA), is possibly a (2,3) so we don't know and make the count NA. I suspect this is not the intended logic, but a

OK. We have now three suggestions to repair the text: - remove the text - add "not" at the beginning of the text - add at the end of the text a warning; something like: "Note that in this case the standard estimates of the parameters are in general not correct, and hence also the t values and the p value. Also the number of degrees of freedom is not correct. (The parameter

Dear all, I am very grateful that Wolfgang Viechtbauer implemented the standardised mean change for dependent groups. I was playing around a bit today, and I am not sure if I understand the "SMCR" procedure correctly. The documentation states that sd1i and sd2i are needed, but it seems to me that SMCR is ignoring sd2i (so Variances are not pooled). Instead, it uses sd1i (pre-test sd),

Dear All, I have been checking the metafor package against R-devel. R CMD check --as-cran metafor yields one note: FOSS licence with BuildVignettes: false Yes, I have 'BuildVignettes: FALSE' in my DESCRIPTION file.

Dear All, There might be a bug in heatmap(): x <- matrix(rnorm(10*5), 10, 5) heatmap(x, labCol=1:5) Error in axis(1, 1L:nc, labels = labCol, las = 2, line = -0.5, tick = 0, : 'at' and 'labels' lengths differ, 5 != 10 Works fine under 4.0.1. Looking at the code from 4.0.1 vs. Rdevel, esp. this part sticks out: labRow <- labRow[rowInd] %||% rownames(x) %||%

Indeed: Using 'weights' is not meant to indicate that the same observation is repeated 'n' times. As I showed, this gives erroneous results. Hence I suggested that it is discouraged rather than encouraged in the Details section of lm in the Reference manual.
