Small functions included in package spatialsegregation, used for manipulation of forest datasets which
have dbh-values (pp with an element $dbh).
clean.up.data(pp, dbh = 10, atleast = 10)
freqs(pp)
minusID(pp, minusR, dbh, atleast=0)
shake(pp, a = 0.001)Multitype point pattern (see package 'spatstat')
Include specii with abundance atleast atleast.
Include only those points with dbh atleast dbh.
Range from the border withing which to exluce points (used for correction of estimates).
Size of displacement: x+Unif(-a,a), y+Unif(-a,a).
Small functions to manipulate multitype point patterns.
clean.up.data: Returns a subsample fullfilling the given constrains.
freqs: Returns the abundance vector.
minusID: Returns a 0-1-vector indicating inclusion in a simple minus-correction.
shake: Shakes the pattern, i.e. adds a random displacement shift to each point.
