similar to: Subsetting a data.frame degenerates at one column?

Hi, I have a simple question about matrix/data frame manipulation. I have a data frame that looks a something like this X Y Z 1 0 "apples" -1 -1 "oranges" ... 0 -1 "bananas" and I'd like to pull out all the rows for which X and Y are (un)equal into a submatrix. How can I do that? Many thanks, Roger Levy

Hi everybody, I have an experiment examining risky choice behavior where two groups of subjects were unevenly divided across two different MRI scanners while they performed a task. Each subject's data was recorded once and only once on a particular scanner. The table describing the distribution of subjects across the scanner (3TE and 3TW) and groups is below. 3TE 3TW Group1 10

Hi everybody, I've written a function to run an LME model on data derived from functional magnetic resonance images. When I run the function with contrasts included I get the following error Error in eval(expr, envir, enclos) : object 'inModelFormula' not found I think it has something do do with the way contrast evaluates arguments, but I've got no idea how to fix it. The code

Good day, Firstly, I am very new to this project. I have dug through some of the documentation, but cannot find a satisfying answer to some questions I have. I hope somebody here can edify me. I am interested in embedded a LLVM 'VM' inside an embedded ARM-based device. That is, I want to be able to load and execute .bc files directly in an embedded system. The questions: -

Most of my IMAP access is achieved by 'ssh $mailhost exec dovecot --exec-mail imap'. I'm testing Dovecot 2.0, and this doesn't seem to work any more ? and I can't seem to work out how to make it work. The wiki page at http://wiki2.dovecot.org/Upgrading/2.0 has no mention of it. I looked through the git history to find the commit that broke it and see if I could find the

RPART doesn't seem to handle the degenerate case when all training samples are drawn from a single class: > TrainType [1] 0 0 0 0 > TrainDat V1 V2 V3 V4 V5 1 0.6434392 0.5105860 0.3048803 0.3161728 0.5449632 2 0.1710005 0.5973921 0.1267061 0.6146834 0.7299928 3 0.6919125 0.8880789 0.9123243 0.9061885 0.9553663 4 0.3094843 0.6475508

What should findInterval(x,vec,all.inside=TRUE) return when length(vec)<=1, so there are no inside intervals? R-3.3.0 gives a decreasing map of x->output when length(vec)==1 and -1's when length(vec)==0. Would '0' in all those cases be better? > findInterval(x=c(10, 11, 12), vec=11, all.inside=TRUE, rightmost.closed=FALSE, left.open=FALSE) [1] 1 0 0 >

Hello everybody! We have a interesting issue about dovecot behavior here. First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot. We realized that dovecot are comsuming more CPU, and this consumption is growing day by day. When we starts dovecot, it runs between 40%-45% of CPU consumption and our old

If there is no free space, the free space allocator will try to get space from the block group with the degenerated profile. For example, if there is no free space in the RAID1 block groups, the allocator will try to allocate space from the DUP block groups. And besides that, the space reservation has the similar behaviour: if there is no enough space in the space cache to reserve, it will reserve
