Converting spatialPointsDataFrame into ppp
From the help of as.ppp {maptools}
data(meuse)
> class(meuse)
[1] "SpatialPointsDataFrame"
attr(,"package")
[1] "sp"
coordinates(meuse) = ~x+y
zn1 <- as(meuse["zinc"], "ppp")
zn1
And then try this:
Kest(zn1)

Hi! Is it possible (and if yes, how) to convert from an spatialPointsDataFrame to a ppp object (selecting the appropriate variable in the dataframe) so that I can run Kest ? I've tried with as.ppp with no success. (I always have a bad time converting among the different spatial objects in R, I promise contributing a flow chart soon, or is ti included in the new book?). Thanks!
