Dear all,

I am using the package spatstat, for analysis of inter and intra species
spatial patterns.

PPPData is may ppp object, and I am using formulas like:

Js<- Jcross(PPPData,"Aun","Qfa")
plot(Js, sqrt(./pi)~r, ylab="L(r)", main="L function Aun,Qfa")

Js<- Jest(PPPData)
plot(Js, sqrt(./pi)~r, ylab="L(r)")

Js<- Jcross(PPPData,"Aun","Qfa")
plot(Js, sqrt(rs/pi)~r, ylab="L(r)", main="L function Aun,Qfa")

The problem is that the resulting plots have theoretical line away from 0
value.
Therefore I think I am not getting the correct L-function. which is the
standardized Ripleys' K function and thus should have theoretical line (of
CSR) at 0 (zero)..?!

Could you please help me on this?

Regards,
Sara Mouro
