Summarizing spatiotemporal clustering result

summary.spotoroo() is the summary method of the class spotoroo. It is a simple wrapper of summary_spotoroo().

Usage

# S3 method for spotoroo
summary(object, ...)

Arguments

object

spotoroo object. A result of a call to hotspot_cluster().

...

Additional arguments pass to summary_spotoroo()

Value

No return value, called for side effects

Examples

# \donttest{

  # Time consuming functions (>5 seconds)


  # Get clustering results
