O-ring statistic
...tic included in one of the packages in R?
This kind of functionality is available in the R package `spatstat'
(available on CRAN or from www.spatstat.org)
According to the cited website, the O-ring statistic is a rescaled
version of the pair correlation function between two types of points:
O_12(r) = lambda_2 g_12(r)
In spatstat, pair correlation functions are computed by the function
'pcf'. To estimate the cross-type pair correlation function,
you do something like
pcf(Kcross(X, 1, 2))
where X is a marked point pattern containing points of types 1 and 2.
To estimate the i...
