Full_Name: Krzysztof Podgorski Version: R version 2.4.1 (2006-12-18) OS: Windows XP Submission from: (NULL) (130.235.3.79) The function ''det'' works improperly for a singular matrix and returns a non-zero value even if ''solve'' reports singularity. The matrix is very simple as shown below. A <- diag(rep(c(64,8), c(8,8))) A[9:16,1] <- 8 A[1,9:16] <- 8

In plotmath expressions, R's degree symbol, e.g. shown by plot(1, main = parse(text = "1*degree*C")) has sunk to halfway the text line, instead of touching its top. In older R versions this looked much better. -- Edzer Pebesma Institute for Geoinformatics Heisenbergstrasse 2, 48151 Muenster, Germany Phone: +49 251 8333081

r-devel list, I have recently written an R package that solves a linear least squares problem, and computes the multivariate normal density function. The bulk of the code is written in C, with interfacing code to the BLAS and Lapack libraries. The motivation here is speed. I ran into a problem computing the determinant of a symmetric matrix in packed storage. Apparently, there are no explicit

Dear R users, even if this question is not related to an issue about R, probably some of you will be able to help me. I have a square matrix of dimension k by k with alpha on the diagonal and beta everywhee else. This symmetric matrix is called symmetric compound matrix and has the form a( I + cJ), where I is the k by k identity matrix J is the k by k matrix of all ones a = alpha - beta c =

In the following plot, the y label is missing if it is too long. x11(type="Xlib") plot(1:5, 1:5, ylab="Do, a deer, a female deer") # missing label plot(1:5, 1:5, ylab="Do") # label is present All is well for x11(type="cairo") This is true both under R devel 2017-09-01 on xubuntu (my desktop), and 3.4.1 on Centos 6.9 (department

When i tried to install the hunspell package, I got this error message: Error: package ?Rcpp? 0.12.3 was found, but >= 0.12.12 is required by ?hunspell?

Or, to avoid accusing you of lying. what you think is "vanilla" probably isn't. What exactly did you do?

I was actually able to reproduce this on a relatively fresh install of 18.04 (a virtualbox). Paul, did you run apt update && apt upgrade before trying to reproduce?

Your last statement is extremely unlikely to be true. The dplyr package should not be present in a vanilla environment, so there should be no such conflict. -- Sent from my phone.

Hi All, I'm trying to add a 'rug' representation of my data to a plot created with densityplot(). While I can do this in the simple case, I can't do it properly when I include the "groups" argument. I have an example below. I am running a reasonably new version of R. print(sessionInfo()) R version 2.12.0 Patched (2010-11-07 r53537) Platform: i686-pc-linux-gnu

I'm using caret to assess classifier performance (and it's great!). However, I've found that my results differ between R2.* and R3.* - reported accuracies are reduced dramatically. I suspect that a code change to kernlab ksvm may be responsible (see version 5.16-24 here: http://cran.r-project.org/web/packages/caret/news.html). I get very different results between caret_5.15-61 +

Dear list, I'm facing an issue with the automated documentation of a function using roxygen2. The function has a complex-valued default argument, which is picked up by roxygen2 using formals() to generate the corresponding Usage section of the Rd file. Unfortunately, it appears that formals() reformats complex numbers. Consider the example below, test <- function(a = 1+2i){} >
