Summary of smerc_cluster object

Description

Summary of object of class smerc_cluster.

Usage

## S3 method for class 'smerc_cluster'
summary(object, ..., idx = seq_along(object$clusters), digits = 1)

Arguments

object	An object of class smerc_cluster.
...	Additional arguments affecting the summary produced.
idx	An index vector indicating the elements of object$clusters to print information for. The default is all clusters.
digits	Integer indicating the number of decimal places.

Value

A data.frame with columns:

nregions	The number of regions in the cluster.
max_dist	The maximum intercentroid distance between all the regions in the cluster.
cases	The number of cases in the cluster.
ex	The expected number of cases in the cluster.
rr	Relative risk in the cluster window. This is (cases/pop)/((total_cases - cases)/ (total_population - population)).
stat	The test statistic for the cluster.
p	The p-value of the test statistic associated with the cluster.

Examples

data(nydf)
coords <- with(nydf, cbind(x, y))
out <- scan.test(
  coords = coords, cases = floor(nydf$cases),
  pop = nydf$pop, nsim = 49,
  longlat = TRUE, alpha = 0.2
)
# summarize all clusters
summary(out)
# summarize clusters 1 and 3
summary(out, idx = c(1, 3))
