Cryptic error message from namespaceExport
Dear Michael,
my package has setOldClass("inla") and the NAMESPACE
contains exportClasses(inla) and importFrom(INLA, inla.posterior.sample)
the old version of INLA uses the S3 class "inla" but does not export it.

Dear all,
Today I got this error message (R 3.6.1) when installing my package:

My package was using setOldClass("inla") and exported the "inla" class via

hyper-parameters
I'm searching a method to estimate the hyper-parameters in arima models.
I'm reading about r-inla package, but in the examples section only talk
about the AR part of the arima, but i need help about the MA part too.
I'm beginner in Bayesian methods, I'm reading the documentation about dlm
package and kalman filters, but the computacional cost of inla i think is

Cryptic error message from namespaceExport
Just to clarify, your package is exporting a class that is not
defined? Or is it exporting a class that is defined by a dependency
and then masked by setOldClass()? A simple reproducible example would
help.

glmmPQL and spatial correlation
Hi all,
I'm running into some computer issues when trying to run a binomial model
for spatially correlated data using glmmPQL and was wondering if anyone
could help me out.
My whole dataset consists of about 300,000 points for which I have a suite
of environmental variables (I'm trying to come up with a habitat model for
a species of seal, using real (presence) and simulated dives

Mixed effects model with a phylogenetic tree/ distance matrix as a random effect
Hi,
I'm trying to build a mixed-effects model in which I'd like to include
either a distance matrix or a phylogenetic tree as a random effect.
The troubles I've had are that:
1. Function lmer() in package lme4 only accepts a data frame column as a
random factor and not a distance matrix.
2. Function MCMCglmm() in package MCMCglmm only accepts a rooted and

linear functional relationships with heteroscedastic & non-Gaussian errors - any packages around?
Hi,
I have a situation where I have a set of pairs of X & Y variables for
each of which I have a (fairly) well-defined PDF. The PDF(x_i) 's and
PDF(y_i)'s are unfortunately often rather non-Gaussian although most
of the time not multi--modal.
For these data (estimates of gas content in galaxies), I need to
quantify a linear functional relationship and I am trying to do this

finite mixture model (2-component gaussian): plotting component gaussian components?
Dear Knowledgeable R Community Members,
Please excuse my ignorance, I apologize in advance if this is an easy question, but I am a bit stumped and could use a little guidance.
I have a finite mixture modeling problem -- for example, a 2-component gaussian mixture -- where the components have a large overlap, and
I am trying to use the "mclust" package to solve this problem.

Simulation of Multivariate Fractional Gaussian Noise and Fractional Brownian Motion
Dear R Helpers,
I have searched for any R package or code for simulating multivariate
fractional Brownian motion (mFBM) or multivariate fractional Gaussian noise
(mFGN) when a covariance matrix are given. Unfortunately, I could not find
such a package or code.
Can you suggest any solution for multivariate FBM and FGN simulation? Thank
you for your help.
Best Regards,
Ryan

using MCLUST package to estimate a poisson-gaussian process
Hi All,
I am using em() function to estimate a poisson-gaussian process from a
univariate one dimension time series, but not sure how to do. In the help
manual, it specify that in "pro" of the argument "parameter", if the model
includes a Poisson term for noise, there should be one more mixing
proportion than the number of Gaussian components. But in the example, the

Gaussian Quadrature Numerical Integration In R
Hi All,
I am trying to use A Gaussian quadrature over the interval (-infty,infty) with weighting function W(x)=exp(-(x-mu)^2/sigma) to estimate an integral.
Is there a way to do it in R? Is there a function already implemented which uses such weighting function.
I have been searching in the statmode package and I found the function "gauss.quad(100, kind="hermite")" which uses

inverse gaussian distribution of frailty variable
Hello,
I'm Emanuela, I'm implemented a survival analysis and I'm trying to use a frailty model with inverse gaussian distribution, but I'm not able to find the right code, because it seems to be only a gamma and a gaussian distribution. Is there also the inverse gaussian distribution?
Thanks a lot
