Hi, I tried to use strsplit for separating a string with || like strsplit(string,"\\||") but it returned each single character was separated. For example: strsplit("a||bc","\\||") [[1]] [1] "a" "" "" "b" "c" where I want the result to be "a" and "bc". Any ideas? Thanks! Best,

Hello all, To calculate the power of a matrix, I used the command "mtx.exp(X, n)", but there is an error saying "Error: couldn't find function "mtx.exp"". How can I deal with this problem? Jing

Hi, I am reading the book "Mixed Effects Models in S and S-Plus" and come across an example with the Rail data. I tried to use lm(travel~Rail,data=Rail) and got the following result: Call: lm(formula = travel ~ Rail, data = Rail) Residuals: Min 1Q Median 3Q Max -6.6667 -1.0000 0.1667 1.0000 6.3333 Coefficients: Estimate Std. Error t value Pr(>|t|)

Yes, keep the $(lsb-release -cs) there. This allows you to change the version of the OS without having to change anything else (for instance we are migrating all of our docker to 24.04 LTS right now, so we only have to modify the FROM entry and all of our Dockerfile will still work).

Hi Marco, Thank you for the follow up email. In the line below, do I replace $(lsb-release -cs) with jammy (Ubuntu 22.04) or leave it alone: Add-apt-repository ?deb https://cloud.r-project.org/bin/linux/ubuntu jammy-cran40/? It?s good to know about installations for Bioconductor. I am not currently using it, but I may need it in the future for other projects. Br, Lauren -- Lauren J. Gerber

Lauren, little oversight from my Dockerfile, if you want to follow the CRAN steps and get the R from the cloud.r-project.org server, you want to replace && add-apt-repository -y "ppa:marutter/rrutter4.0" With && add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/" The ppa repo is Michael Rutter personal repo

Hi All, Does anyone have experience successfully installing and loading the R package ?ggbreak? in a Docker container? I ask because I have successfully used the ?ggbreak? package in a script outside the Docker container (on my local computer), but for some reason, I get the following error message when trying to load it using library(ggbreak) or library(?ggbreak?) inside the same script that

Is there a RoR best practice wrt determing in a visitor''s browser has JS disabled? Is there even a way to find out? I''ve got a couple of pages in my app that are not going to degrade gracefully at all. I really need to point a visitor who has JS disabled down a seperate path. Any ideas?

You may want to look into using the log option to qnorm e.g., in round figures: > log(1e-300) [1] -690.7755 > qnorm(-691, log=TRUE) [1] -37.05315 > exp(37^2/2) [1] 1.881797e+297 > exp(-37^2/2) [1] 5.314068e-298 Notice that floating point representation cuts out at 1e+/-308 or so. If you want to go outside that range, you may need explicit manipulation of the log values. qnorm()

ng, I have a matrix (x) with binary content. Each row of the matrix holds exactly one 1, and the rest of the row is zeros. The thing is that I need to 'collapse' the matrix to one column where each row holds the original column index of the 1's (y). Sometimes, the matrix is quite large, so I have a perfomance problem. x <- matrix(c(1,0,0, 0,0,1, 0,1,0, 0,0,1, 0,1,0,

Dear R list, I calculated a two-sided p values according to 2*(1-pnorm(8.104474)), which gives 4.440892e-16. However, it appears to be 5.30E-16 by a colleague and 5.2974E-16 from SAS. I tried to get around with mvtnorm package but it turns out to be using pnorm for univariate case. I should have missed some earlier discussions, but for the moment is there any short answer for a higher
