similar to: 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! --

Thank you. This is a very useful idea!

It works.

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

I've searched the doc for insert and could not find the way to do the following, hope someone can help: Let's say we have a vector: > a [1] "1" "2" "3" "5" "6" "3" and we want to insert a "7" after any given "3", i.e., we want vector a to become: [1] "1" "2" "3"

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

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 would like to do some fairly basic stem-and-leaf displays in R. I am aware (I might even say painfully aware) of stem(base) and have tried it. That's why I'm hoping someone has a usable stem- and-leaf display for R so that I don't have to write my own. r-project.org > Search > R Site Search > "stem and leaf display" finds nothing. I also tried the mail archive

Thanks for the feedback. At least on Windows, the font size for View() appears to be controlled by the font size specified under the Rgui preferences / Rconsole. I thought that under Linux, it might be controlled by some .Xresources/.Xdefaults setting. Ok, will wait for a bit but if nobody else has any suggestions, I'll ask on r-devel.

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

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.

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

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

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.
