Distance between a vector and matrix rows
I am trying to find the distance between a vector and each row of a dataframe. I am using the function "distancevector" in the package "hopach" as follows: mydata<-as.data.frame(matrix(c(1,1,1,1,0,1,1,1,1,0),nrow=2)) V1 V2 V3 V4 V5 1 1 1 0 1 1 2 1 1 1 1 0 vec <- c(1,1,1,1,1) d2<-distancevector(mydata,vec,d="euclid") The Euclidean distance between the two rows of the d...

newbie: new_data_frame <- selected set of rows
...en extract top five hits my_dataframe <- read.table("myDB.csv", header=F, dec=".", sep=";", row.names=1) #reads the whole file scaled_DB <- scale(my_dataframe, center=FALSE) #scales the values require(hopach) #checks necessary R package distances <- order(distancevector(scaled_DB, scaled_DB['query',], d="euclid")) #calculates distances and orders the results from lowest for(i in distances[1:5]) print( dbfile[i,]) #prints top five hits just for debugging What I want to do: 1) create a small top_five frame sadly this does not work: for(i in dist...

[LLVMdev] Dependence Analysis [was: Flow-Sensitive AA]
...this as an analysis and make following changes. - Rename LoopMemDepAnalysis as DataDependenceAnalysis. Various transformation passes will use this interface to access data dependence info. This is an external interface. Put this in include/ llvm/Analysis. - Make DirectionVector (and later on DistanceVector) independent interface and put them in ADT. - Put various tests, DeltaTest, in lib/Analysis folder. The transformation pass does not need to see these details. - DataDependenceAnalysis will select various dependence tests based on user selection. We want a interface similar to AnalysisGroup...

Sure. For now, I am posting it as an attachment, because it does not build against the current SVN version. It is really basic (for example, it cannot produce distance vectors,

Wojtek, Please see David's message below. Have you or can you check in your code, perhaps as a project for now? That will allow us to start looking at it and perhaps collaborating on it. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Aug 20, 2008, at 3:05 PM, David Greene wrote: > On Wednesday 20 August 2008
