A function to estimate the inhomogeneous pair correlation function for a spatiotemporal point process. See equation (8) of Diggle P, Rowlingson B, Su T (2005).

time interval contained in the interval xyt$tlim over which to compute average. Useful if there is a lot of data over a lot of time points.
Vector of values for the argument r at which g(r) should be evaluated (see ?pcfinhom). There is a sensible default.
choice of edge correction to use, see ?pcfinhom, default is Ripley isotropic correction
Whether or not to suppress warnings generated by pcfinhom
other parameters to be passed to pcfinhom, see ?pcfinhom
