Dear all, In MATLAB, to generate multivariate F with specified correlation matrix Pn I can use the code such as Z = mvnrnd([0 0 0 0 0], Pn, N); U = normcdf(Z,0,1); X = [finv(U(:,1),5,15) finv(U(:,2),5,15) finv(U(:,3),5,15) finv(U(:,4),5,15) finv(U(:,5),5,15)]; Is there something similar in R? Thank you for your time.

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

Dear all, I'm looking for a function that calls the inverse F-distribution. Something equivalent to FINV in matlab or excel. Does anyone know if such a function already exists for R? (I haven't been able to find one.) Thanks for any leads. Best, Jennifer

Dear R useRs, I have a problem with nls.lm function of minpackl.lm package. I need to fit the Van Genuchten Model to a set of data of Theta and hydraulic conductivity with nls.lm function of minpack.lm package. For the first fit, the parameter estimates keep changing even after 1000 iterations (Th) and I have a following error message for fit of hydraulic conductivity (k); Reason for

I believe this may be more related to analysis than it is to R, per se. Suppose I have the following function that I wish to integrate: ff <- function(x) pnorm((x - m)/sigma) * dnorm(x, observed, sigma) Then, given the parameters: mu <- 300 sigma <- 50 m <- 250 target <- 200 sigma_i <- 50 I can use the function integrate as: > integrate(ff, lower= -Inf, upper=target)

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

Dear all, Trying to test for heteroskedasticity I tried several test from the car package respectively lmtest. Now that they produce rather different results i am somewhat clueless how to deal with it. Here is what I did: 1. I plotted fitted.values vs residuals and somewhat intuitively believe, it isn't really increasing... 2. further I ran the following tests bptest (studentized

I have data that ranges from 0.3 to 2 and I want to change the scale to be from 0 to 1. Can this be done in R? -- Thanks, Jim. [[alternative HTML version deleted]]

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
