different randomForest performance for same data
Hello, I came across a problem when building a randomForest model. Maybe someone can help me. I have a training- and a testdataset with a discrete response and ten predictors (numeric and factor variables). The two datasets are similar in terms of number of predictor, name of variables and datatype of variables (factor, numeric) except that only one predictor has got 20 levels in the training

dimnames in pkg "ipred"
Hello List, I`m trying to make prediction using a bagged tree with the package ipred. I tried to follow the manual but I`m getting an error message. Also browsing through the list-archive I didn`t find any hint. Maybe someone can help me? selbag <- bagging(SOIL_UNIT ~., data=traindat.bin, coob=TRUE) Error in dimnames(X) <- list(dn[[1L]], unlist(collabs, use.names = FALSE)) :

findInterval(all.inside=TRUE) for degenerate 'vec' arguments
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 >

Subsetting a data.frame degenerates at one column?
Greetings. At the moment, I'm applying R to some AIX 'nmon' output, trying to get a handle on some disk performance metrics. In case anyone's interested: http://docs.osg.ufl.edu/tsm/pdf/ some of them are more edifying than others. (ahem) I'm trying to develop a somewhat general framework for plotting these measures, in the hopes that it's of some use to people other

Degeneration of CPU Performance
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 First, the scenario: We have 2 server running with the same load, one with our old pop3 solution (out of date) and other with Dovecot.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

[RFC][PATCH 1/2] Btrfs: try to allocate new chunks with degenerated profile
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
