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

I am nearing the end on a project i have been working on and am trying to figure 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

...PI. Dhould the driver be modified to not return battery.charge if the UPS returns 0xFF? Are there other variables that are affected? (I don't think the IDG400 is covered in the protocol documentation that the NUT project received a while back.) > > For the point number 2, as we know NUT perfomrs the shutdown after battery low signal with a delay of 5 seconds as specified in the FINALDELAY. > Is this correct? Right, NUT tells the computer to shut down, but it also typically sends a shutdown signal to the UPS. Does the IDG400 also respond to the same shutdown command as others?

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, I am using errorest function from ipred package. I am hoping to perform "bootstrap 0.632+" and "bootstrap leave one out". According to the manual page for errorest, i use the following command: ce632[i]<-errorest(ytrain ~., data=mydata, model=lda, estimator=c("boot","632plus"), predict=mypredict.lda)$error It didn't work. 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. Win9x boxes can no longer login. So , I examine the problem and it appears that things are ok but none of the things samba is supposed to be doing is happening. Again this box serves many operations on
