Hi all, I'm doing a very informal and unscientific poll: which kernel do you use on your CentOS machines? Not which version of the CentOS kernel, but which repository. Here are some examples I can think of off the top of my head: ==CentOS stock ==build own from CentOS SRPMs ==kernel-ml (from ELRepo) ==kernel-lt (from ELRepo) ==OpenVZ kernel ==build own from kernel.org ==other? One reason

Hi, I'm pretty new to ocfs2 and a bit stuck. I have two Debian/Squeeze (testing) machines accessing an ocfs2 filesystem over aoe. The filesystem sits on an lvm2 volume, but I guess that is irrelevant. Even when mostly idle, everything accessing the cluster sometimes hangs for about 20 seconds. This happens rather frequently, say every 5 minutes, but the interval seems irregular while the

Hi I just did an update to lates trunk ================= context "Given a generated venue_spec.rb with fixtures loaded" do fixtures :venues specify "fixtures should load two Venues" do Venue.should have(2).records end end ================== gives me ========== 1) TypeError in ''Given a generated venue_spec.rb with fixtures loaded fixtures should load two

I manually downloaded the rpart package and installed it using dpkg, without removing the old rpart package first, and now everything works. During the installation, dpkg said: Unpacking r-cran-rpart (4.1-13-1cran1xenial0) over (4.1-13-1cran1xenial0) So again, it seemed that the new version had been installed, but it really wasn?t. I had no idea that something like this could happen. Huh.

Hello, I would like to annotate a graph with the expression 'alpha = 5%' (the alpha should be displayed as the greek letter). I tried > text(1,1,expression(alpha == 5%)) which gives a syntax error. escaping the percent sign (\%) or doubling (%%) does not help. What do I do?

> At the dev meeting I heard Doug Gregor say something like, "what kind of dirty animals are you, you just push directly to master!?" Based on that, I think other communities may set up workflows where they push branches to places, and some automation rebases and updates master asynchronously, optionally conditioned on some (light) testing or approval. Someone has already mentioned

Hi all, Probably a rudimentary question. I have a flat file that looks like this (the real one has ~10e6 elements): 10110100101001011101011 and I want to pull that into R as a vector, but with each digit being it's own element. There are no separators between the digits. How can I accomplish this? Thanks in advance! Matt -- Matthew C Keller Asst. Professor of Psychology University of

Hi, all, I pressed Ctrl+C in R process, and found that the child process which was spawned by using "pipe" is terminated due to this. Are there any way to work around it, so that the child process can run happily without being terminated? Or can we block the signal for the child process? 1. I used pipe to spawn one C++ process, which will running in a loop without exiting immediately.

The cells are interpreted as counts, so by scaling you're analyzing a different experiment (one with fewer observations). So the chi-squared value will change (the terms (O-E)^2/E in the statistic scale linearly ignoring rounding and "Yates' continuity correction"). The chisq.test on the original data is a test of association. Conventionally you decide ahead of time on a

Dear R users I have a problem with predict.tree() when I want the fitted values of a tree object to be returned (i.e. argument 'newdata' is missing). Whatever I specify for argument 'type' the fitted model object is returned. Example: library(tree) data(kyphosis) fit.tree <- tree(Kyphosis ~ Age + Number + Start, data=kyphosis) p <- predict(fit.tree,

I am making a barplot using barplot2 from gplots where each bar represents a specific tree species. I have formatted the species names on the x-axis so that the genus name is above the species name and have then rotated the labels 45 degrees to save room. This is my code: >columncolor<-c("grey20", "grey20", "grey20", "grey70",

Hello, I just upgraded my Ubuntu Xenial system to R 3.5.1 (from 3.4.?) by changing the sources.list entry and doing an "apt-get dist-upgrade". Everything works except loading the rpart package in R: > library(rpart) Error: package or namespace load failed for ?rpart?: package ?rpart? was installed by an R version with different internals; it needs to be reinstalled for use with

Hi all, I'm giving a talk in a few days to a group of psychology faculty and grad students re the R statistical language. Most people in my dept. use SAS or SPSS. It occurred to me that it would be nice to have a few concrete examples of things that are fairly straightforward to do in R but that are difficult or impossible to do in SAS or SPSS. However, it has been so long since I have used

Hi all, Is there a way to skip non-sequential lines using the "skip" argument in the scan function? E.g., I have a matrix with 100 rows and 1e7 columns. I open a connection and want to read only lines 5, 7, 9, etc [i.e., seq(5,99,2)] It might seem that the syntax to do this would be something like this (if only the "skip" allowed vectors in the same way colClasses does in

+1--this is the single most-annoying issue with R that I know of. My usual solution, after accomplishing nothing as R spins idly for a couple hours, is to kill the process and lose any un-saved work. save.history() is my friend, but is a big delay when you work with big data sets as I do, so I don't run it after every command. I have cc'd r-help here, however, because I experience this

Hi there, We''ve been using previous version of bdrb (drb based one) for a while and it was running relatively OK. We recently attempted to upgrade to the new version to keep up / use supported version but we ended up reverting to the older version. Here are the things that moved us to revert : 1) With the workers we never manage to pass this error: '''' You have a nil
