nls() is using 1) only a Gauss-Newton code which is prone to some glitches 2) approximate derivatives Package nlmrt uses symbolic derivatives for expressions (you have to provide Jacobian code for R functions) and an aggressive Marquardt method to try to reduce the sum of squares. It does return more information about the problem (singular values of the final Jacobian and gradient at the proposed

Hi to all, Is there a way we can fit a non linear model to a data using non linear least square method without necessarily initialising the parameters of the model. I find it hard to get the initial value of the parameter. Below is a sample of the code I have. *nachman<-nls(OARmedium$OCCUPANCY~1exp(-alpha*OARmedium$MEAN^beta),start=list(alpha=0.2,beta=0.1),data=OARmedium)summary(nachman)*

Hi to All, I am building a package in R and whenever I run command "R CMD build OAR" in the terminal, I get the following error: * checking for file ?OAR/DESCRIPTION? ...

I'm working on an integration that uses QCOW2 volumes with backing stores. I have qemu configured to run as the "qemu" user, which seems to be fine. I now need to make sure my volumes are readable by this user. However, it seems the volume being created is owned by root, instead of "qemu" as I'd expect it to be. I tried various things and was unable to get it to create

Hey, I'm having problems with samba. It has never worked properly on my server since I've had it installed.. Its for a home server, running xbox-Linux Fedora Core 6. I've just uninstalled every trace of the old samba, and started a fresh. With the latest samba sources I found on the website. The nmbd starts fine, but smbd never starts, and in the kernel log, I get the following

I''ve got 3 different sets of public ips, each with it''s own static ips, and default gateways, and only one physical ethernet port. I''d like to be able to setup domUs that use the various ips, and route through the gateway for that particular IP. My problem is that when I setup these ip addresses as alias on eth:0, only one set of ips/netmask/gateway will work. any

Hello, If anyone happens to run into an issue with trying to mount/use image files with libguestfs when ksplice is installed on the host system. This is the workaround. Create file: '/usr/lib64/guestfs/supermin.d/zz-ksplice-workaround' with the following contents: /sbin/depmod.ksplice /sbin/ksplice-depmod /sbin/modprobe.ksplice /sbin/modprobe.ksplice-orig /sbin/depmod.ksplice-orig You

When viewing a list of network computers with Windows Explorer, it shows the server names and the server strings, i.e.; Bobs computer in accounting (WS1), where (WS1) is the netbios name. Is there any way to get the server string to show on Linux? It'd be nice to see it in Nautilus, but I know I'll have to ask them. If there were a Samba utility that would retrieve it, that would do
