Generalized version of the get.pi
function that takes in an arbitrary function and
returns the probability that a point within a particular range of a point of interest shares the relationship
specified by the passed in function with that point.
1 | get.pi(posmat, fun, r = 1, r.low = rep(0, length(r)), data.frame = TRUE)
|
posmat |
a matrix with columns x, y and any other named columns

fun |
a function that takes in two rows of

r.low |
the low end of each range, 0 by default |
data.frame |
logical indicating whether to return results as a data frame (default = TRUE) |
pi value for each distance range that we look at. Where:
π(d_1, d_2) = \frac{∑ \boldsymbol{1} (d_{ij} \in [d_1,d_2)) \boldsymbol{1} (f(i,j)=1) }{∑ ∑ \boldsymbol{1} [d_{ij} \in (d_1,d_2)) \boldsymbol{1} (f(i,j) \in \{1,2\}) }
