density {Riemann}

S3 method for mixture model : evaluate density

Description

Compute density for a fitted mixture model.

Usage

density(object, newdata)

Arguments

object

a fitted mixture model of riemmix class.

newdata

data of n objects (vectors, matrices) that can be wrapped by one of wrap.* functions in the Riemann package.

Value

a length-n vector of class labels.

Examples

# ---------------------------------------------------- #
#            FIT A MODEL & APPLY THE METHOD
# ---------------------------------------------------- #
# Load the 'city' data and wrap as 'riemobj'
data(cities)
locations = cities$cartesian
embed2    = array(0,c(60,2)) 
for (i in 1:60){
   embed2[i,] = sphere.xyz2geo(locations[i,])
}

# Fit a model
k3 = moSN(locations, k=3)

# Evaluate 
newdensity = density(k3, locations)
