haz.ppp(W)
W |
a data frame or matrix with two or three columns (coordinate x, coordinate y, and mark of the point) |
This naive function easily transform your xy data to the format required by spatstat (version <2.0). It establishes the window of observation as the rectangle defined by the xy range. It asumes that the first two columns are coordinates x and y, and the third (if any) gives the marks of the points.
A point pattern with the format of spatstat v. < 2.0
