Hello, I want to solve a nonlinear 3SLS problem with "nlsystemfit()". The equations are of the form y_it = f_i(x,t,theta) The functions f_i(.) have to be formulated as R-functions. When invoking "nlsystemfit()" I get the error Error in deriv.formula(eqns[[i]], names(parmnames)) : Function 'f1' is not in the derivatives table

Hello, Is there a possibility of setting parameter constraints in nls.lm() ? The documentation does not say anything on that explicitly. In order to achieve the same effect, the criterion function could be penalized outside the valid domain. Is that a correct procedure? Kind regards, Kilian [[alternative HTML version deleted]]

Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea?

As it turns out, on cards that actually have CRTCs on them we're already calling drm_kms_helper_poll_enable(drm_dev) from nouveau_display_resume() before we call it in nouveau_pmops_runtime_resume(). This leads us to accidentally trying to enable polling twice, which results in a potential deadlock between the RPM locks and drm_dev->mode_config.mutex if we end up trying to enable polling

Is there a way to use R as a client server application? Whitch means: 1. install R on a server (running as a service) 2. from client send R-scripts through IDE/Editor (TINN-R) to "R-server" 3. receive R-output on client All the Best Kilian Schwab

Hello. I try to compute a "White-corrected" ANOVA. Therefore I use the command "Anova" implemented in the car()-package): Anova(modelname, white.adjust="hc3") and receive the error message: "Fehler in SS[i] <- SS.term(names[i]) : nichts zu ersetzen" (German) "Error in SS[i] <- SS.term(names[i]) : nothing to replace" (probably being the

Hi there, I'm new to R but I thought this is the most likely place I could get advice or hints w.r.t the following problem: I have a series of measurements xi with associated uncertainties dxi. I would like to construct the probability density histogram of this data where each density estimate has an associated error that is derived from the dxi. In other words, for large dxi the

Hello, i have a linux box running samba as a fileserver for 4 Windows NT 4.0 Workstations. the performance is good on responing-times but loading and writing large files (more than 500 kByte) is too slow. All the users ale working as guest-users. Can this be the cause for my problem? This is my smb.conf file: **************************************************************************** [global]

Hi rsync developers, I'm trying to get some fancy mirroring done with selecting files from a larger archive through the --files-from option. The only problem that I do see is that rsync will not eat the --delete option whatever I try. Thus, all the old files remain in the mirror archive instead of being deleted. To be more clearly, I want the rsync --files-from option to behave like

Hi all, I'm working with a dataset from 10 treatments, each treatment with 30 subjects, each subject measured 5 times. The plot of the dataset suggests that a 3-parameter logistic could be a reasonable function to describe the data. When I try to fit the model using gnls I got the message 'Step halving factor reduced below minimum in NLS step'. I´m using as the initial values of the

I just accidently sent a partially complete email, so this contains the rest (sorry!)

Hi: The gls function I used in my code is the following fm<-gls(y~x,correlation=corARMA(p=2) ) My question is how to extact the AR(2) parameters from "fm". The object "fm" is the following. How can I extract the correlation parameters Phi1 and Phi2 from "fm"? These two parametrs is not in the "coef" componenet of "fm". Thanks a

Hi Has anybody done THD or THD-N measurements with the CELT Codec (bext would be on various bit rates) If someone could share results for Mono at 64kBit and Stereo at 128 and 196kBit it would be great. thank you very much Jochen -------------- next part -------------- An HTML attachment was scrubbed...

Dear R users; Ive got two questions concerning nlme library 3.1-65 (running on R 2.2.0 / Win XP Pro). The first one is related to augPred function. Ive been working with a nonlinear mixed model with no problems so far. However, when the parameters of the model are specified in terms of some other covariates, say treatment (i.e. phi1~trt1+trt2, etc) the augPred function give me the following
