confused with indexing
...that looks like the following (I am sorry that this is not a reproducible example)
indexSkipped<-NULL
....code Skipped that might alter indexSkipped
if (length(indexSkipped)==0)
spatial_structure<-spatial_structures_from_measurements(DataList[[i]]$Lon,DataList[[i]]$Lat,meanVector)
else

What I am doing here is that I am processing files. Every files has a measurement table and Longtitude and Latitude fields. If one file i...

Estimating bivariate normal density with constrains
Dear R-Users
I would like to estimate a constrained bivariate normal density, the
constraint being that the means are of equal magnitude but of opposite
signs. So I need to estimate four parameters:
mu (meanvector (mu,-mu))
sigma_1 and sigma_2 (two sd deviations)
rho (correlation coefficient)
I have looked at several packages, including Gaussian mixture models in
Mclust, but I am not sure what is the best way, or the best package to use
for this task.
Greatly appreciate any suggestions!
