similar to: xyTable(x,y) versus table(x,y) with NAs

x <- c(1, 1, 2, 2, 2, 3) y <- c(1, 2, 1, 3, NA, 3) > str(xyTable(x,y)) List of 3 $ x : num [1:6] 1 1 2 2 NA 3 $ y : num [1:6] 1 2 1 3 NA 3 $ number: int [1:6] 1 1 1 NA NA 1 How many (2,3)s do we have? 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

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 what xyTable() is doing here and nobody bothered to correct me. I now stumbled again across this issue. x <- c(1, 1, 2, 2, 2, 3) y <- c(1, 2, 1, 3, NA, 3) table(x, y, useNA="always") xyTable(x, y)

I correct myself. Obviously, the line first[is.na(first) | isFALSE(first)] <- FALSE should read first[is.na(first)] <- FALSE Serguei.

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, 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")

Thank you. This is a very useful idea!

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

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

AFAIR, it is a little more subtle than that. If you have replication weights, then the estimates are right, it is "just" that the SE from summary.lm() are wrong. Somehow, the text should reflect this. It is of some importance when you put glm() into the mix, because you can in fact get correct results from things like y <- c(0,1) w <- c(49,51) glm(y~1, weights=w,

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 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) =

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.

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

My local R-devel version now has (in ?lm) Non-?NULL? ?weights? can be used to indicate that different observations have different variances (with the values in ?weights? being inversely proportional to the variances); or equivalently, when the elements of ?weights? are positive integers w_i, that each response y_i is the mean of w_i unit-weight observations

Since the three posters agree (only) that there is a bug, I propose to file it as a bug, which is the least we can do now. There is more to it: the only other case of a change in the Reference Manual which I know of, is also about the weights option! This is in coxph. The Reference Manual version 3.0.0 (2013) says about coxph: " ... If weights is a vector of integers, then the estimated

Hi Wolfgang, I can test your package, please send it to me in private. Btw. I only have an x86 machine, and no sparc, so if your problem is sparc-specific, then my test is probably useless.

Peter, This is a highly structured text. Just for the discussion, I separate the building blocks, where (D) and (E) and (F) are new: BEGIN OF TEXT -------------------- (A) Non-?NULL? ?weights? can be used to indicate that different observations have different variances (with the values in ?weights? being inversely proportional to the variances); (B) or equivalently, when the elements of

You can probably already do this using the \if{html} conditional, and either including the matchjax js files in the package, or getting them from a CDN.
