The default nstart in ?bigkmeans is 1. Try ans<-bigkmeans(data,k,nstart=8) Good luck

Hi, all, I have a really big matrix that I want to run k-means on. I tried:
data <-
read.big.memory('mydata.csv',type='double',backingfile='mydata.bin',descriptorfile='mydata.desc')
I'm using doMC to register multicore.
library(doMC) registerDoMC(cores=8) ans<-bigkmeans(data,k)
In system monitor, it seems only one thread running R. Is there anything I did wrong? Thanks in advance for any suggestions. Best, Lishu ? ? ? ?[[alternative HTML version deleted]]
