Use of MathJax (or something similar) in .Rd files
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") remotes::install_github("wviechtb/mathjaxr") Package authors can then use the \loadmathjax macro to enable its use and the \mjeqn{latex}{ascii} and \mjdeqn{latex}{ascii} macros for including inline and displayed equation...

Use of MathJax (or something similar) in .Rd files
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

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

Finding Missing Data Patterns
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

Help with improving efficiency
Dear All, I have a problem that I think could be solved much more efficiently, but I don't have a clue how to accomplish this. I have a matrix W with dimensions k*(p+1): Let's say W is 5*4 and looks like this: > W [,1] [,2] [,3] [,4] [1,] 1 -1 -1 1 [2,] 1 1 1 1 [3,] 1 2 -2 -1 [4,] 1 0 -1 -1 [5,] 1 -2 -1 0 I want to take

Indexing Elements of a Dataframe

Equations as arguments to functions
I am trying to pass an equation as an arguement to a function, which seems pretty straightforward given lazy evaluation. I constructed the following little test to make sure I sort of knew what I was doing: go <- function(X,eq) { C <<- X*2; d <<- eq} a _ rnorm(100) go(10,eq=a[.5*length(a)]+C+1) > C [1] 20 > d [1] 21.10551 > a[.5*length(a)] [1] 0.1055086 Everything

Outer with Three Vectors
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

Title with substitute and paste
Hello All, I am generating some plots where the title is generated with substitute and paste. An example: nval <- 20 plot(0,0) title(substitute(paste("n = ", n), list(n = nval))) But when compared to: plot(0,0) title("n = 20") the title in the first plot looks slightly different (it is not in bold). How can I get the two titles to look exactly the same? Also, how can I

Changing pch spacing
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! --

Tested Random Number Generator
Dear All, The editor of a journal to which I had submitted a publication asked whether R has a "tested random number generator." My paper included Monte Carlo simulations generating random normal and random chi-square values. help(rnorm) lists Wichura, M. J.
