I don't know the Russell-Rao coefficient but maybe this will help: You can compute the number of times y and x are both 1 (that's what your function f does) by counting 1s in y*x, i.e., sum(y*x), aka t(y)%*%x. Ordinary matrix multiplication does this row-by-column, so if M and N are two binary matrices, M%*%t(N) will have (i,j) entry equal to the count of 1s in common to row i of M and

Dear all, which font do I have to choose to use German umlauts at x/ylab in plot? Do I have to change Rdevga; and how? Or should I use these Hershey vectors? I looked quite a long time for a solution, which should be easy, so I thought I'd better ask here. Maybe some other people have already solved this problem.

Hello, a. is there a possibility to obtain a distance matrix with the cosine between vectors?? hclust, hierclust, dist will not work and seem to be hard to extend. b. if there is not: Is the cosine between vectors implemented somewhere?

Hello, a. when I use hclust with the methods media, centroid, and mcquitty, and plot the results, the dendrograms have lines that are crossing each other. Is this ok? b. My next question refers to plot.dendrogram: How can I use parameters as "hang" or "cex" here? E.g. for st <- as.dendrogram(subtreeshc[[x]]) I would like to have something like this, where cex and hang

Hi, i can store the disk of a guest in a plain partition which isn't formatted. That's no problem, i did it already several times, although the promised speed increase didn't appear. But is it possible to create from such a guest a snapshot in a .sn file using virsh ? Regards, Bernd -- Bernd Lentes Systemadministration Institut für Entwicklungsgenetik Gebäude 35.34 - Raum

Hi, i have a two-node cluster with several domains as resources. During testing i tried several times to migrate some domains concurrently. Usually it suceeded, but rarely it failed.

Hi all, The call parallel::makeCluster(1L) hangs infinitely on my MacOS machine which seems to be already reported by some people (e.g., https://stat.ethz.ch/pipermail/r-devel/2018-February/075565.html). However, the solutions posted on SO, GH or R-devel do not work in my case. So far, I unsuccessfully tested ? 1. Couple of reboots 2. Adding 192.0.0.1 to /etc/hosts 3. Using R.app

Within an user function, how are the warnings from an R function be trapped (such that some proper actions can be taken)? 'last.warning' is returned only at the top level.

Hi Thomas, thanks for your reply (and thanks for your patience...). I am now using the following minimal reprex: > library(parallel) > cl <- makeCluster(2L) I freshly started the machine and did not open any other app. Just R.app (3.6.1). After executing the second line of code, R seems to hang infinitely and does not respond. The R process itself uses almost no CPU. Unfortunately,

Hello to all, I am using ArcView 3.2 under Wine. For now I have been able to do what I need, except for the projection utility... it seems that I am missing some dll, but I have no clue which ones could be... If somebody knows the solution, please let me know. I am new to Wine, and have no clue how to search for the right dll... Thanks a lot to all of you and to this great Wine-project!!! Petra

Dear everyone, I have looked all over the internet but I cannot find a way to solve my problem. In my data I want to sum a couple of variables. Some of these variables have NA values, and when I add them together, the result is NA dat <- data.frame( id = gl(5,1), var1 = rnorm(5, 10), var2 = rnorm(5, 7), var3 = rnorm(5, 6), var4 = rnorm(5, 3), var5 = rnorm(5, 8) ) dat[3,3] <- NA dat[4,5]

Okay, admittedly I'm running an old version 2.0.5, but, why do I have to set the eXecute permission in Linux before Samba will let a Windows client see any files? Why would execute have anything to do with read and/or write? I would think I could set -rw-rw---- or -rw-rw-rw- and be just fine, but oh no, you get an empty list and cannot create new files until I change it to -rwxrwx--- or

Dear experts, when trying to estimate an kernel density function with density(x) I get the following error message with imported data from either EXCEL or text files: Error in density(spr) : argument must be numeric. Other procedues such as truehist work. If I generate data within R density works fine. Does anybody have an idea? Yours -- Christoph Hanck Wissenschaftliche Hilfskraft

Hello again, I'm glad to tell you that I fixed that error. It was gcc compiler error and I found the solution right here: https://askubuntu.com/questions/26498/choose-gcc-and-g-version (this link was sent by Harutyun Khachatryan). I changed the versions of gcc and g++ from 4.3 and 4.4 to 4.8 and 4.9 and it worked. I also posted the solution in the gist I've sent you before. Thank you
