as.numeric and as.character with locale using comma as separator
Dear all, summary: My LC_NUMERIC is changed from C to de_DE by library (qtbase). [which shouldn't happen according to the warning when setting it back manually]. I posted an issue at their github repository, but maybe the behaviour is a bit more of general interest. However, if LC_NUMERIC is changed, as.character () uses the decimal separator that belongs to LC_NUMERIC (and not options

`mgp[1:3]' are of differing sign (PR#14130)
Full_Name: Cornell Gonschior Version: 2.10.0 OS: Linux Submission from: (NULL) (212.201.28.40) Hi, in the introduction to R, you can find the following sentence in the par() chapter: "Use tck=0.01 and mgp=c(1,-1.5,0) for internal tick marks." I thought that's nice, because I wanted to have tick marks and tick labels inside and the axis title outside. But: > plot(z, las=1,

Dear all, I am new R user and I am sure that this question has been asked quite often and I have also googled it and read about it!

Installing lumi and hdrcde
To whom it may concern. As I would like to analyse some array data I was keen on downloading the lumi package that depends obviously on hdrcde that is not available for r 2.12.1. I did not find instructions to solve or circumvent this problem. Installing hdrcde by hand did not work either. It was not detected by > (.packages(all.available=TRUE)) if installed in the R library. Thanks Hermann

reference classes: question on inheritance
Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def
