SpatialPoints-class {sp} | R Documentation |
Class for (irregularly spaced) points
Objects can be created by calls of the form SpatialPoints(x)
.
coords
:Object of class "matrix"
, containing the
coordinates (each row is a point)
bbox
:Object of class "matrix"
, with bounding box
proj4string
:Object of class "CRS"
, projection string
Class "Spatial"
, directly.
signature(x = "SpatialPoints")
: subsets the points; only
rows can be subsetted
signature(from = "SpatialPoints", to = "data.frame")
:
retrieves the data part
signature(from = "SpatialPoints", to = "SpatialPixels")
: equivalent to assigning gridded TRUE for a copy of the object
signature(from = "SpatialPointsDataFrame", to = "SpatialPixelsDataFrame")
: equivalent to assigning gridded TRUE for a copy of the object
signature(from = "data.frame", to = "SpatialPoints")
: sets
coordinates, which may be in a data frame
signature(from = "matrix", to = "SpatialPoints")
: set
coordinates, which may be in a matrix
signature(obj = "SpatialPoints")
: retrieves
the coordinates, as matrix
signature(x = "SpatialPoints", y = "missing")
: plot points
signature(object = "SpatialPoints")
: summarize object
signature(x = "SpatialPoints")
: add point symbols to plot
signature(object = "SpatialPoints")
: prints coordinates
signature(object = "SpatialPoints")
: rbind-like method
