How to show which variables include in plot of classification tree
Dear all For my research, I am learning classification now. I was trying some example about classification tree pakages, such as tree and rpart, for instance, in Pima.te dataset have 8 variables (include class=type): library(rpart) library(datasets) pima.rpart <- rpart(type ~ npreg+glu+bp+skin+bmi+ped+age,data=Pima.te, method='class') plot(pima.rpart, uniform=TRUE) text(pima.rpart)

mann whitney u
Dear Sir, I am comparing two samples using wilcox.test in R. Literature appears to describe mann whitney u test as the most appropriate test to use on my data. is the wilcox.test function equivalent to mann-whitney u? Is there a way to gain the U-value as apposed to the W-value in R? Thank you

Mann-Whitney U

Here is the code i have so far... group1 <- c(LeafArea2) group2 <- c(LeafArea1) wilcox.test(group1, group2) This code works for datasets with the same number

Regarding the project "Create LoopNestPass"
Hi, Thanks for your help! I've checked the sources that you mentioned. Currently, I think that I would need to implement a FunctionToLoopNestPassAdaptor which is essentially the same as the FunctionToLoopPassAdaptor but operates only on LI.getTopLevelLoops(). We might also need a LNPMUpdater (LoopNestPassManagerUpdater) which disallows adding inner-loops back into the pipeline, and

Regarding the project "Create LoopNestPass"
Hi, I would like to give a quick update on what my current design and implementation go like. Basically, the `FunctionToLoopPassAdaptor` is now modified to a generic version `FunctionToLoopUnitPassAdaptor`, which allows re-using the existing codes to implement `FunctionToLoopNestPassAdaptor`, with the help of additional metadata associated with `Loop` and `LoopNest`.

[GSoC] Prospective student for Unify ways to move code or check if code is safe to be moved
Hi Rithik, CodeMoverUtils is not aimed for only loop transformations, it can be used by any transformation which want to move code or check if code is safe to be moved. It can currently do both hoist and sink but require control flow equivalent between the original location and the intended to be moved location. I would like to keep the API decoupled from loop, so other transformation can use it.

How to clean/reset glusterfs config?
Hello, I'm trying to set up an experimental gluster storage cluster using virtual machines (VMs) on Xen. I want to be able to instruct the VMs to "forget" any previous gluster configuration (i.e. the server to forget about all previously configured peers, the peers to forget what storage volumes they are providing, etc). The use case is that the VMs will can be attached to
