Dear friends, suppose i have two datasets: A and B A: id<-1:6 x<-c(1,2,3,4,5,6) y<-c(2,4,6,8,3,2) xy<-data.frame(id,x,y) B m<-c(1,1,3,3,5,5) n<-c(2,2,6,6,3,3) mn<-data.frame(m,n) Now, i want to perfomr two tasks: 1. get a subset of B,no duplicate values,: C: m n 1 2 3 6 5 3 2.Extract the values in A on the conditions that x=m and y=n the results should be: id x y 1 1 2 3

...e out where to host it. I am very tempted to host it on google''s app engine. you get a ton of space, band width, and processor all for free! I was hoping to get some advice as to what people think about deplying on the app engine. Would it better to wait until ruby is supported? Are there perfomrance issues with using JRuby? What would happen if ruby were supported in the future, would transfering be a pain?

Hi, for zfs raidz1, I know for random io, iops of a raidz1 vdev eqaul to one physical disk iops, since raidz1 is like raid5 , so is raid5 has same performance like raidz1? ie. random iops equal to one physical disk''s ipos. Regards Victor -- This message posted from opensolaris.org

Hi Charles, attached there is a patch for a new version of riello drivers: Changes: - small changes in riello_usb.c and riello_ser that solved problem with UPS that not support realtime autonomy calculation (and also internal temperature); - the second problem I think is related to the first because the shutdown command that I sent to UPS by NUT monitor works without problems; Cheers, Elio

Hi, I am using errorest function from ipred package. I am hoping to perform "bootstrap 0.632+" and "bootstrap leave one out".

I then tried the

Greetings, I have a FreeBSD 3.1 and Samba 2.0.5a box doing domain logons and file sharing to about 250+ desktops and upgraded about 21 days ago I have encountered something very interesting.
