)

`tobs`	The vector of observed test statistics in descending order for non-overlapping windows.
`pvalue`	The pvalues associated with `tobs`.
`alpha`	The significance level to determine whether a cluster is signficant. Default is 0.1.
`noc_info`	An object from the `noc_nn` function.
`z`	An indicator vector indicating which observations are cases.
`N`	Number of event locations
`N1`	Number of case events
`x`	A `ppp` object with marks for the case and control groups.
`d`	A matrix of intercentroid distances for the event locations.
`maxd`	The radius of the largest possible cluster to consider. Default is `NULL`, i.e., half the maximum intercentroid distance.
`longlat`	A logical value indicating whether Euclidean distance (`FALSE`) or Great Circle (WGS84 ellipsoid, `FALSE`) should be used. Default is `FALSE`, i.e., Euclidean distance.
`nsim`	The number of simulations from which to compute the p-value. A non-negative integer. Default is 499.
