unitname(x) <- value"ppx").unitname.print.ppx the value is NULL.
For unitname.ppx an object of class "units".print, plot,
unitname and unitname<-
for the class "ppx" of multidimensional point patterns.
The print method prints a description
of the point pattern and its spatial domain. The unitname method extracts the name of the unit of
length in which the point coordinates are expressed.
The unitname<- method assigns the name of the unit of length.
