R doesn't find SpatialPoints or SpatialPointsDataFrame

Question

I'm trying to create SpatialPoints objetcs from data frame on R

natFPV <- SpatialPointsDataFrame(coords = coordinates(natFPv.per_data[,c(27,28)]),data = natFPv.per_data[,-c(27,28)])
natFPV <- SpatialPoints(coords = coordinates(natFPv.per_data[,c(27,28)]))

But getting the error for both:

Warning: Error in SpatialPoints: could not find function "SpatialPoints"

I'm really don't konw how to deal it.

• Bera: Have you imported the library with library(sp)?

Answer 1

You need to load the library with:

library(sp)

You need to do this once in each session, unless you customize your environment to automatically load it each time
