Error using function MVN in package MCLUST: Fortran symbol name not in DLL for package

Hi All,

I need to fit a mutlivariate normal model to a dataset in order to obtain the mean and covariance parameters. I see that the MVN function in the MCLUST package can do this, however when I try to run even the simplest example provided in the documentation, as below, I get the following error:

n <- 1000
set.seed(0)
x <- rnorm(n, mean = -1, sd = 2)
mvn(modelName = "X", x)

Error in .Fortran("mvn1d", as.double(data), as.integer(n), double(1),  : 
  Fortran symbol name "mvn1d" not in DLL for package "mclust"

I cannot see a resolution to this in the list, and wonder whether I need to load something else separately to the package? Could it be that I need to load a separate DLL?

Many thanks for your help.

I suspect at a minimum we need the basic information requested in the
posting guide: your OS, version of R< version of the package in question.

sessionInfo() is a useful command.

You shouldn't need to load anything beyond the package itself.

Please the footer of this message.  It works for me, and we need the 
'at a minimum' information we asked for to begin to guess what might 
be wrong for you.

However, this is pretty much overkill: there is nothing 'mutlivariate' 
about your example, and even if there were mean() and var() give the 
standard parameter estimates.
