Hello world, I am actually transferring a course in data management for students in biology, geography and agriculture from statistica to R - it works surprisingly well. If anyone is interested in my scratch/notepad (in German language), please see www.hydrology.uni-kiel.de/~schorsch/statistik/statistik_datenauswertung.pdf (pages 40-52) The dataset is:

Hello everyone, My progress has stalled on finding a way of creating a somewhat complicated variable to add to my existing dataframe and I am hoping one of you could help me out. The dataframe below contains only a fraction of the data of my complete dataframe, but all of the variables. What I want to do is add another variable named 'WEEK' to this dataframe that is assigned 1 for row 1

R users, Hello, I used sqlFetch to import a data table from MS Access 2007 and I set as.is = TRUE to prevent character vectors from becoming factors. However, I can't figure out how to prevent the $ operator from being added by sqlFetch to the end of each character vector(e.g. TD$ and SITE$). This causes subsequent parts of my code not to work and also results in some behavior that I

R experts, I am working with a fairly large data set comprised of 563 rows by 116 columns including several different modes. I have been unable to read in the data set completely using the read.table function and the RGui (i.e. nearly half the total number of rows are missing from the data set along with the column names). The data does read in fully using Tinn-R's Rterm; however, at several

Hi, I have a requirement to run my gluster hosts within a firewalled section of network and where the consumer hosts are in a different segment due to IP address preservation, part of our security policy requires that we run local firewalls on every host so I have to get the network access locked down appropriately. I am running 3.5.2 using the packages provided in the Gluster package repository

Hi! Anyone else experiencing performance problems when using the new monorepo? My experience is that performance of gitk (and git log) sometimes is really bad when working in the monorepo. I've mainly seen it when using gitk on specific files/directories, but since gitk seems to be using "git log --no-color -z --pretty=raw --show-notes --parents --boundary HEAD -- <file>" it

Dear all, I want to do a F test, which involves calculation of the degrees of freedom for the residuals. Now say, I have a nlme object "mod.nlme". I have two questions 1.How do I extract the degrees of freedom? 2.How is this degrees of freedom calculated in an nlme model? Thanks.

Dear R users, A have a dataframe (matrix) with two collumns (plot, and diameter (d)). I want all diameters values for different combination of plots. For example I want all d values for all posible combination, 100C2 (all d values for plot 1 with all d values in the plot 2.......with all d values from plot 1 with all d values from plot 100, ...... with all d values from plot 99 with all d values

Dear R users, Something is strange in summary and IQR. Suppose, I have a data set and I would like to find the Q1, Q2, Q3 and IQR. x<-c(2,4,11,12,13,15,31,31,37,47) > summary(x) Min. 1st Qu. Median Mean 3rd Qu. Max. 2.00 11.25 14.00 20.30 31.00 47.00 > IQR(x) [1] 19.75 However, I test the same data set in SAS "proc univariate", and SAS shows that

I'm experimenting with 6.2 now. Things seem to be really great so far! Distribution closure is one of my favourite pets. So I tried to install everything. I found only one problem, but that's another (minor) thing. But I found almost nothing under /usr/lib. So, Biarch is really dead? Funny! A couple of years back, I finally opted for CentOS instead of Debian just because of Biarch

Hi, I'm having especially hard time today and couldn't find any clue/answer through the internet. ?I hope you can help.

Hello, I'm cc'ing R-Help. Sorry but your question was asked 3.5 years ago, I really don't remember it.

I'm building my own openmpi packages derived from upstream SRPMs. Problem: The ones built with Intel's compiler can only be installed by force, because Intel doesn't register their provided libs with rpm. Any idea how this can be done? (Alternative ideas are appreciated as well -- as long as they don't read as: make Intel fix this.) -Michael

Namely: * hivex * hivex-devel * librdmac * librdmac-devel * sanlock-libs * sanlock-devel and maybe others. Is this on purpose (I don't know if upstream has removed or updated the 32-bit rpms, but the old ones are still in C6.3/x86_64), or is it just the usual sloppyness (I've been told here on previous occasions the biarch is a pain in the ass to maintain, nobody cares anyway,

Gnome's control-center now requires NetworkManager-wifi. But it's only a soft requirement, no shared libs involved. To keep your workstation NM-free, you want to install a dummy package that provides NetworkManager-wifi but actually contains nothing, ideally before updating to 7.5. Here's a script to create such a dummy: https://github.com/larsks/fakeprovide If you do this,
