similar to: randomForest: more than one variable needed?

Dear all, Can anybody give me some hint on the following error msg I got with using randomForest? I have two-class classification problem. The data file "sample" is: ---------------------------------------------------------- udomain.edu udomain.hcs hpclass 1 1.0000 1 not 2 NA 2 not 3 NA 0.8 not 4 NA 0.2 hp 5 NA 0.9 hp ------------------------------------------------------------ The

Hi, I am using the Random Forest Package, and want to do an automatic rerun using only those variables that were most important in the original run. Is there anybody who has experience with this and can give me helpful suggestions?

Hello Han, Thanks for the response. The XML option with qemu:commandline works if the device is added during the VM creation. But I would like to hot-plug the device to the running VM. I can add the device using the command line <virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0> But I would like to add the device using the XML file, like <virsh attach-device VM-Name

For the libvirt 5.8 release, I find that there is a new comment in qemu.conf: #slirp_helper = "/usr/bin/slirp-helper" It indicates that there is a slirp-helper to help setup slirp network. But I cannot find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and libvirt (v5.9.0-rc1-2-g73f91d659b). Could you please tell me where I can find that helper program? Thanks --

Hi Han, thanks for your reply. I'm using KVM as hypervisor. The versions are: Kernel: 4.5.2 Libvirt: 1.3.4-1 But its quite embarrasing... when I was answering your mail I was having a look if there is a new kernel I can build, since I have to rely on some patches. I upgraded from 4.4.3 to 4.5.2 and now libvirt doesn´t have any problem. So thanks for the heads up! Regards Alex On Tue, May

Hello, As we know, libvirt sanlock support file type storage. I wonder *if it supports network storage.* I tried *iSCSI*, but found it didn't generate any resource file: Version: *qemu-2.10 libvirt-3.9 sanlock-3.5* 1. Set configuration: qemu.conf: *lock_manager = "sanlock"* qemu-sanlock.conf: *auto_disk_leases = 1disk_lease_dir = "/var/lib/libvirt/sanlock"host_id =

I have a problem that deals with correlating wind velocity to seed collection data. The problem lies in that I have a wind data set that is contains 2000+ data points and weed collection data on the order of a couple hundred. Both data sets were collected for the same time period, but there is not a one-to-one wind velocity->seed location match. My understanding of correlation is that you

Hi Team, I am exploring "edu" device in QEMU to add my own custom device. I am able to add the device using the command line. Would it be possible to add the device using XML file through libvirt? -- Regards, Bharath

Hi, I wonder if the function "density" outputs the gaussian mixture formula that is estimated from the input data, assuming a gaussian model is used at each data point ? I want to take the derivative of the finally estimated gaussian mixture formula for further analysis. Thanks in advance for any help that you can offer me! Hui

I am new to R and I'd like to use the randomForest package for my thesis (identifying important variables for more detailed analysis with other software). I have found extremely well written and helpful information on the usage of R. Unfortunately it seems to be very difficult to find similarly detailed tutorials for randomForest, and I just can't get it work with the information on
