cprod: Cross product of integration points

Description

Calculates the cross product of integration points in different dimensions and multiplies their weights accordingly. If the object defining points in a particular dimension has no weights attached to it all weights are assumend to be 1.

Usage

cprod(...)

Arguments

...

data.frame or SpatialPointsDataFrame objects, each one usually obtained by a call to the ipoints function.

Value

A data.frame or SpatialPointsDataFrame of multidimensional integration points and their weights

Examples

# NOT RUN {
# }
# NOT RUN {
# ipoints needs INLA
if (bru_safe_inla()) {
  # Create integration points in dimension 'myDim' and 'myDiscreteDim'
  ips1 <- ipoints(rbind(c(0, 3), c(3, 8)), 17, name = "myDim")
  ips2 <- ipoints(domain = c(1, 2, 4), name = "myDiscreteDim")

  # Calculate the cross product
  ips <- cprod(ips1, ips2)

  # Plot the integration points
  plot(ips$myDim, ips$myDiscreteDim, cex = 10 * ips$weight)
}
# }
# NOT RUN {
# }
