Dear all, Here I come with another stupid question. Suppose I want to use nls() to fit a series of data (here modelled by generated points), then plot the points and the fitting curve. I figured out some way of doing it: x <- runif(1:20, 0, 10) y <- 0.1*x^2 - rep(3, length(x)) + rnorm(length(x), sd = 0.5) yfit <- nls(y ~ a*x^2 + b*x + c, start = list(a = 1, b = 1, c = 1),

Hello, Fitting a piecewise smooth curve to a set of points (and a piecewise linear function in particular) seems to be a recurring question on this list. Nevertheless, I was not able to find an answer to a question that bothers me. Suppose I have the following data set, and would want to fit it with a piecewise smooth curve, In this model data, one curve is valid for up to 3 and another one for

Hello everybody, Is it possible to coax legend() into displaying more than one simbol per line in legend? I have a graph like the one attached to this mail; I would like to reorganize the legend in such a way that the duplicate text would be omitted, i.e., the first line would read <square> <triangledown> "increasing frequency" and the second one would read <circle>

Dear all, when working on a project with embedded R, I found out that R-2.0.0 causes a problem where older versions worked OK. Rf_findVar(...) causes the following error when used to find a generic function (such as print): fun = Rf_findVar(...); R_tryEval(fun, ...); Error in function (object, ...) : Invalid generic function in usemethod Alternatively, using Rf_findFun(...) seems OK in this

chan_sip.c6524 reload_config= unable to get ip address from asterisk, sip disabled The ip address is working fine, Internet works great. Can anyone help...Thanks

Hello ! I am having troubles setting up Busy Light Fields (BLF) in asterisk 1.4.18 The things work up to 80%, I can transfer the call by BLF button and I can see the green (free) status and red (busy) status. What I cannot do is to accept the call when someone rings a remote extension. The BLF button starts to blink in red telling me that the call is ringing on remote extenson, but if I press it,

Hi people, I have a problem with samba, openldap and the creation of machine accounts. I don't know if here is a good place to ask but I don't receive help in other places.. I read many guides, howto's, etc. but I can't get around with the solution... I have seen an older message to another list (mail.gna.org) asking for the same problem that I have, it was: -

I'm recurrently falling into two null pointers when building some LLVM objects: raw_fd_ostream and Twine. On both ctors, the char* is never asserted to point somewhere. I know I have to make sure the string exists, but would be good to get an assert instead of a segfault. It'd reduce debugging time a lot on those cases. Is it against the "LLVM way"? I haven't seen many

First of all, I apologize for asking a question that has appeared recurrently in this mailing list. However, I have googled for it, have looked at the mailing list archives, and also looked at Pinheiro & Bates book (although not very thoroughly, I must confess), to no avail. Here is the question: I am trying to obtain with lme or lmer the same exact numerical results (p-values) that I obtain

Hi, I have started getting the following error message when I run the repadmin showreps command on the Windows Server 2008 server that is my primary DC: DsReplicaGetInfo() failed with status 8453 (0x2105): Replication access has been denied.

Hi all, I've been trying to run a model using R2winBUGS, and recurrently I get the message: "Error in FUN(X[[3L]], ...) : invalid to change the storage mode of a factor" My model is the following: sink("GLMM_Poisson.txt") cat(" model{ mu~dnorm(0,0.01) beta1~dnorm(-1,1) for(j in 1:nsite){ alpha[j]~dnorm(mu.alpha,tau.alpha) } mu.alpha~dnorm(0,0.01)

Hello everyone, I'm using Samba 3.0.30 as PDC in my home-LAN, the clients are all XP Pro SP2. Everything is working as it should, although I notice an annoying and quite random login delay of 1-5 seconds for all user-machine combinations. The log lines below (log-level 2) are for example what I got about an hour ago: [2009/03/20 18:43:45, 3] smbd/open.c:open_file(240) Tester opened file

I'm a bit of a noob w/ samba and I set up a small samba shar (v. 3.4.0) on my ubuntu machine which hosts a shared drive for a single vista laptop (my wife's machine). My question is .. is it normal for her to regularly be asked to enter her username and password or is it something that I've done in my configuration. Note: I used the configuration guide from Linux Journal

Hi, we have a couple of Linux RHEL 5 samba servers in a domain, one as PDC and the other as BDC, and both with LDAP backends samba version is 3.0.28-1 We want pc clients can't change their machine password using sambaRefuseMachinePwdChange policy, so we set it to 1 in LDAP But pc clients still can change their passwords, and we don't see any acces to sambaRefuseMachinePwdChange

Hi all, I'd like to authenticate my fresh Samba installation against an LDAP server without the Samba schema. Obviously I cannot touch it. So I'd like to use LDAP just for the authentication without getting the UID and the other parameters from it. I can use the same UID, home folder and so on for all the users, the only important thing is to provide access only to the LDAP users. Is

Hello! I have previously posted this question on llvm-bugs, but I was redirected and asked to post to llvmdev, so I'm resending this message to this mailing list. I am interested in LLVM, particularly for the implementation of a programming language, and have been looking at the LLVM documentation recently. However, I was wondering what exactly do these two lines, extracted from the

Hello! I have been considering using LLVM for my compiler project for some time now, and have been extensively researching its capabilities. However, I have come to a sticking point that I cannot solve. My language is a multi paradigm language, but with the emphasis on "functional". As such, it is expected that programs will allocate a lot of small, short-lived data. This means, in

If so, than probably yes... both the pointers would probably be kept in the processor cache, which would speed-wise probably be comparable (will it be?) with keeping variables in the registers. - Tom Primožič -------------- next part
