Dear friends,
I fail to understand and use the class of "SpatialPointsDataFrame", hope
someone to givems some hints on it.
For example:
z<-rnorm(16) # this is attribute data
coords<-cbind(x=c(1,1,1,2,2,2,3,3,3),y=c(1,2,3,1,2,3,1,2,3)) # this is
coordinate data
How should i use SpatialPointsDataFrame to combine them and generate my
dataset, Thanks a lot!
