Greetings, I have a groupedData (nmGroupedData) object created with the following syntax: Soil <- groupedData( ksat ~ conc | soil_id/sar/rep, data=soil.data, labels=list(x='Solution Concentration', y='Saturated Hydraulic Conductivity'), units=list(x='(cmol_c)', y='(cm/s)') ) the original data represents longitudinal observations in the form of:

Hi, I am curious about how to interpret the table produced by anova(ols(...)), from the Design package. I have a multiple linear regression model, with some interaction, defined by: ols(formula = log(ksat * 60 * 60) ~ log(sar) * pol(activity, 3) + log(conc) * pol(sand, 3), data = sm.clean, x = TRUE, y = TRUE) n Model L.R. d.f.

Dear all, I am trying to evaluate the optimisation behaviour of a function. Originally I have optimised a model with real data and got a set of parameters. Now I am creating simulated data sets based on these estimates. With these simulations I am estimating the parameters again to see how variable the estimation is. To this end I have written a loop which should generate a new simulated data

Dear All, I'm having trouble on 2 laptops Lenovo B580 since upgrading to Centos6.5.

hello all happy new year and hope you r having a good holiday. i would like to calculate the expectation of a particular random variable and would like to approximate it using a number of the functions contained in R. decided to do some experimentation on a trivial example. example ======== suppose x(i)~N(0,s2) where s2 = the variance the prior for s2 = p(s2)~IG(a,b) so the posterior is

I found this old post using a Google search for DTMF tones heard during an Asterisk call. The calling party does not hear them, only the called party. We are experiencing this sporadic DTMF "beep" followed by a momentary silence on a random number of our calls. This happens on trunk to SIP and SIP to SIP calls, so it's not PRI related. Since this thread is dated 2003, and the

Hello Damien, I am using OpenSSH-5.0 on my ARM board. I want to perform RSA authentication, but server is not accepting the key generated by the client. I have copied the authorized_keys in the "$HOME/.ssh/" folder and provided permission (755) to that folder. Please help me how to solve this problem. Following is the log from the client OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006

Hola Rubén, Totalmente de acuerdo con los consejos de Carlos. Ten en cuenta que aunque R disponga de varios (bastantes) GB de memoria, algunos de los objetos que va creando durante el proceso pueden consumirla por completo. Es decir, que aunque tu ordenador tenga 64GB de RAM, es posible que no queden 10 GB libres para almacenar un objeto (porque ya hay demasiados objetos grandes en la

Dear Helper, I used "constrOptim.nl" and got the value of par. The estimations looks good even if the number of iterations is only 16. But the values of hessian and convergence are both "NULL". I tested the objective function and gradient function by "optim" and didn't see any problem there. With these functions, "optim" gives the convergence value

I am trying to install asterisk@home on a Dell 1650 server. The setup cd runs fine and completes with no errors but when I try to connect to the web site (http:myip/maint) to edit the configs nothing happens just a page not found error. I'm not sure if there is a problem with my dual on board nics but when I check ifconfig I see the dhcp address info that was assigned for eth0 and then

Yo creo que el problema principal está en betapart.core(), que crea y mantiene simultáneamente en memoria varios objetos de alrededor de 1 Gb que luego combina en una lista... Probablemente es entre las líneas el código de betaper.core donde hay que ir eliminando objetos. Saludos, Marcelino El 22/12/2015 a las 18:26, Carlos J.

Hi, Just wondering if anyone else is able to reproduce this with the current * (CVS 12:15 GMT) Call Snom from any device (tested with i4l, zaptel and SIP). Answer call and try to transfer call using transfer button on Snom. After dialing new number press OK (F4). At this moment the Snom users hears dialtone, but the caller still hears the Snom user... Even hangup on the Snom doesn't

Hi, I have four subnets. Three have a single Samba WINS. One has a Server 2003 WINS. I have no control over the router connect the subnets. I have control over the Samba servers and the S2003. I'd like to have subnet browse lists of all subnets visible on all subnets to all the workstations. Right now I only have each subnet's browse list visible on its subnet, Except for the samba WINS

https://cran.r-project.org/web/views/Optimization.html (Cran's optimization task view -- as always, you should search before posting) In general, nonlinear optimization with nonlinear constraints is hard, and the strategy used here (multiplying by a*b < 1000) may not work -- it introduces a discontinuity into the objective function, so gradient based methods may in particular be

Hi, I am using the lme package to fit mixed effects models to a set of data. I am having a difficult time understanding the *meaning* of the numDF (degrees of freedom in the numerator), denDF (DF in the denomenator), as well as the Intercept term in the output. For example: I have a groupedData object called 'Soil', and am fitting an lme model as follows: ## fit a simple model #

It's an odd network, but it's 2 separate, somewhat related companies on one subnet for shared printers, etc. I am a computer consultant, but am pretty new to Linux/Samba. The first company has a newly installed server with CentOS 3.3 (Red Hat Enterprise Linux 3.3), running Samba 3.0.11. The second company has a Windows 98 "server" on it, which should eventually be upgraded to
