Hi Everyone, I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5) Now, my problem is, how can I get the actual clusters? Thanks! Best, Baoqiang Cao

...of dataframes with the regular lapply function it works correctly. If use the 'parLapply' there is an error message.

Hello all; I'm trying to execute parallel jobs trough library snow on a cluster built through torque/PSB. I'm succesfully obtaining the cluster with: >system("cat $PBS_NODEFILE > cluster.txt") >mycluster <- scan(file="cluster.txt",what="character") >cl <- makeSOCKcluster(mycluster) The only problem, at the moment, is that if I use processors in nodes other that the one in which I'm running R, the communication is extremely slow. If all processor are in the "...

Hello! I created a distances matrix for 13 objects using daisy (see the attached file). I am trying to clusteranalyse it using agnes but it's not working. What might be the problem: mydistances<-read.csv("Results of daisy.csv") mycluster<-agnes(mydistances, method="ward") I am getting: Error in agnes(mydistances, method = "ward") : NA/NaN/Inf in foreign function call (arg 15) I am using R 2.13.1.

Our group has several web apps developed in ColdFusion, PHP, and Rails. The ColdFusion and PHP apps are on an older server, and the Rails apps on a new server. Ideally, we''d like them all to share the same server. Our current setup for the Rails server is Apache2.2 with mod_proxy_balancer and mongrel_cluster. We''d like to have specific directories be processed and served by

...date, but as the whole point of a CA mechanism is to delegate trust, shosts seems a bit redundant in this case. It seems to me like there's a missing piece here, something like an /etc/ssh/authorized_keys, which would allow you to write something in the spirit of cert-authority,hosts="*.mycluster.foo.bar" ssh-... which would then permit hostbased authentication for hosts with a valid certificate matching the hostname pattern without passing further shosts checks.

To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct
