Hi R-colleagues. In the sem-package i have a problem to introduce hidden variables. As a simple example I take an ordinary factor analysis. The program: cmat=c(0.14855886, 0.05774635, 0.08003300, 0.04900990, 0.05774635, 0.18042029, 0.11213013, 0.03752475, 0.08003300, 0.11213013, 0.24646337, 0.03609901, 0.04900990, 0.03752475, 0.03609901, 0.31702970)

Hi everybody! Is there any way to read a postscrit file into R? All the best to you Ralf Finne SYH University of Applied Sciences Vasa Finland

Hi experts! Have anybody experience in including an R-program as part of a larger system? In Matlab there is a toolbox that converts a m-script into C-code. One application in mind is that I do the model building in R, for estimating the risk for cancer based on clinical measurements. When the model is ready, a small R-program can simulate the model to estimate the risk for a new patient. The

Dear Catarina, I prefer to leave the AIC value as NA for the tweedie GLM family because it takes extra time to compute and is only occasionally wanted. It's easy to compute the AIC yourself using the dtweedie() function of the tweedie package.

Dear users; I am doing GLMs with the Gamma distribution, and I always get errors ("no valid set of coefficients: please supply starting values") or warnings ("NaNs produced in log(x)") when I use the links identity or inverse, but I don´t get them if I use the log link. For example: >

Does anyone have any input into integrating asterisk with a alcatel 4400 PBX. Acording to what i've found is that Alcatel uses R2 for E1 -- regards Vikram (http://www.vicramresearch.com)

Hi List. We have an Redhat 8.0 machine who acts as an printserver. I'm sharing printers via Samba and using CUPS. Samba is 2.2.7a and CUPS 1.1.8. The Microsoft clients (Win9x, Win NT, Win 2k) is downloading the driver from the server. I had no problem to install and upload up to 55 printers but now I am not able to set the driver. I can install more printers, but when cupsaddsmb is running

Hi list I have a data frame I would like to loop over. To begin with I would like crosstabulations using the first variabel in the data frame, which is called "meriter". > table(meriter[[1]], meriter[[3]]) ja nej Annan 0

Hi all, Using the FLAC++ level 2 metadata interface the following function doesn't do what you would expect: cuesheet->get_track(i).get_num_indices(); (where cuesheet is a FLAC::Metadata::CueSheet *) It returns a bool instead of an int, why is this? To get the mumber of indicies in a track I need to use: cuesheet->get_track(i).get_track()->num_indices; ie. retrieve the C struct

Dear R users; I am modelling densities of some species of birds, so I have a problem with a great ammount of zeros. I have decided to try GLMs with the tweedie family, but in all the models I have tried I got an NA for the AIC value. Just to check the problem I've compared the a glm using the Gaussian family with the identity link and a glm using the tweedie family with var.power=0 and

Hi everybody! Can anybody help me to find an R-function for the Siegel-Tukey test. Than you in advance. Ralf Finne SYH, University of Applied Sciences Vasa Finland

Hi R fans I am trying to make a program to ask the user to choose data file: print("Choose data file please !") matr=read.table(file.choose(),dec=".",header=TRUE) The problem is that the prompt Choose data file please ! comes after I have chosen the file. What am doing wrong? Thanks in advance Ralf Finne

Hello all, I looking at package dse or vars or mAr I know how to simulate a VAR(p) process, my problem is that most of those processes are unstable (not weakly stationary). Do anybody know how to generate a random VAR (or VARMA even better) process that is weakly stationary? Thanks -- View this message in context: http://r.789695.n4.nabble.com/simulating-stable-VAR-process-tp4261177p4261177.html

Sorry Martin to bother you again! I have an ISDN flux with 100 numbers. The local PSTN is sending now the DNIS/DID (so they said!!!) (I have set the immediate=no in zapata.conf) but I have the same problem as before : NOTE : the number is alphanumeric-DID alphanumeric (I will make tests with numeric mumber!).

This is a general question about Design of experiments. If i am not allowed to post general questions like this here please accept my apologies and ignore the question. I did a DOE with six factors in eight runs. I know i cannot check for interactions using this design, but i tried the interaction plot and it showed me many interactions. After this I foldover the design and ran the 8 runs to learn

hi trevor, well, if you''re controlling whats going over the vpn then there are several options: i''ve been playing with racoon lately (well longer then with freeswan) so i''m not so sure with ipsec, but ... it appears that the meta-data ( i.e. packet marking) is perserved on packets that have not yet been encrypted but are going to be. as a general strategy, i would

Hello, I''m looking for some expert advice since I''m quite a newbie when it comes to programming. I realized that a lot of people(programs) are using the prototype.js and honestly, I cannot see why. Right, prototype has some nice AJAX support but it is lacking a documentation. I recently came accross cross-browser.com and saw their xlibrary - to me it seems that xlibrary
