server:

object of class "character"; contains the location of the server that executes REST.SoilGrids calls

query:

object of class "list"; contains parameters or REST.SoilGrids query

stream:

object of class "character"; contains parameters or REST.SoilGrids stream operation

over

signature(x = "REST.SoilGrids", y = "SpatialPoints"): overlays spatial points and the target grids defined via the REST.SoilGrids-class (point-by-point) and returns list of objects of "SpatialPixelsDataFrame"-class

## Not run: 
library(rjson)
library(sp)
## 2 points:
pnts <- data.frame(lon=c(10.65,5.36), lat=c(51.81,51.48), id=c("p1","p2"))
coordinates(pnts) <- ~lon+lat
proj4string(pnts) <- CRS("+proj=longlat +datum=WGS84")
pnts
## REST example:
soilgrids.r <- REST.SoilGrids(c("ORCDRC","PHIHOX"))
ov <- over(soilgrids.r, pnts)
str(ov)

## End(Not run)
