Geom for SpatialPoints objects
This function coerces the SpatialPoints into a data.frame and uses geom_point
to plot the points.
## S3 method for class 'SpatialPoints' gg(data, mapping = NULL, crs = NULL, ...)
data |
A SpatialPoints object. |
mapping |
Aesthetic mappings created by aes or aes_ used to update the default
mapping. The default mapping is |
crs |
A CRS object defining the coordinate system to project the data to before plotting. |
... |
Arguments passed on to geom_point. |
A geom_point return value
