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

If a value is not supported, the driver should not publish it with the dstate API. Dhould the driver be modified to not return

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

...lda)$error ceLOOB[i]<-errorest(ytrain ~., data=mydata, model=lda, estimator=c("cv"), est.para=control.errorest(k=cv.k,nboot=B), predict=mypredict.lda)$error They worked. However, as I didn't specify "boot" in estimator, I am wondering if "bootstrap" is still perfomred. I set nboot=B in est.para. Thanks in advance. Jenny

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

When I copy an old file to a share the motification time is not changed. Ok, the file has not been modified but since it is new to this share I like to change it's time to the copy time! There MUST be an option to do this!But I haven't found it yet :( Can anyone help? -- Torsten
