German umlaut in xlab
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.

Distance matrix by cosine?
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? Thanks for all hints and advice! Petra Steiner -------------- next part -------------- An HTML attachment was scrubbed... URL:

a. crossing branches with hclust, b. plot.dendrogram
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

MacOS parallel::makeCluster fails
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

box m-test
Hello everybody, Is there in R a so called box m-test for testing the equality of the variance/cov. matrix for checking on homoscedasticity? I could not find it among the traditional packages for multivariate statistics...

is it possible to create a snapshot from a guest residing in a plain partition ?
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

density(x)
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

(no subject)
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

MacOS parallel::makeCluster fails
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,

projection utility in ArcView
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

Fw: Summary for Distance matrix by cosine?
Dear all, below you find enclosed my message from January 9th and my program (attention: beginner). Thanks for both answers! a. However, as far as I know the cosine is not the same as the Pearson correlation (only in special cases). b. Reid Huntsinger's hint was very useful, however I had to transpose the matrix first, for I want to calculate the distance of the _rows_. Regards, Petra

Sum of a couple of variables of which a few have NA values
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]

Linux permissions vs Samba permissions
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

read.table() and scientific notation
Dear all, I am having troubles importing values written as scientific notation using read.table(). I'm sure this is a frequent problem, as many people in my lab have this problem as well, so I'm sure that I just have troubles googling for the right solution. The problem is, that, given a file like that: a 1 2e-4 b 2 3e-8 ... the third column gets imported as a factor, or a string if I

Logit and Probit for Panel data
Dear R users/experts, I've heard it's possible to estimate the above kinds of models in R. However, after (an admittedly brief) survey of the packages, I haven't found an obvious candidate.
