Get the coordinates of a vector type Spatial* object
Extract the coordinates of a Spatial object
## S4 method for signature 'SpatialPolygons' geom(x, sepNA=FALSE, ...) ## S4 method for signature 'SpatialLines' geom(x, sepNA=FALSE, ...) ## S4 method for signature 'SpatialPoints' geom(x, ...) ## S4 method for signature 'data.frame' geom(x, d, gt, crs, ...)
x |
SpatialPolygons*, SpatialLines*, or SpatialPoints* object; or a data.frame |
sepNA |
logical. If |
... |
additional arguments, none implemented |
d |
data.frame that matches the number of objects in data.frame |
gt |
character. geometry type. Must be one of "polygons", "lines", "points" |
crs |
character. PROJ.4 crs string |
Matrix with 6, (5 SpatialLines), or 3 (SpatialPoints) columns. object (sequential object number) part (sequential part number within the object; not for SpatialPoints), cump (cumulative part number; not for SpatialPoints), hole (is this a hole or not; only for SpatialPolygons), x (x coordinate or longitude), y (y coordinate or latitude)
p <- readRDS(system.file("external/lux.rds", package="raster"))
x <- geom(p)
head(x)
# and back to a SpatialPolygonsDataFrame
x <- data.frame(x)
sp <- as(x, "SpatialPolygons")
crs(sp) <- crs(p)
spdf <- SpatialPolygonsDataFrame(sp, data.frame(p), match.ID=FALSE)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
