Most 14C dates have point position information in the coordinates columns lat and lon. This allows them to be converted to a spatial simple feature collection as provided by the sf package. This simplifies for example mapping of the dates.

as.sf(x, quiet = FALSE)

# S3 method for default
as.sf(x, quiet = FALSE)

# S3 method for c14_date_list
as.sf(x, quiet = FALSE)

Arguments

x

an object of class c14_date_list

quiet

suppress warning about the removal of dates without coordinates

Value

an object of class sf

Examples

#> Warning: Dates without coordinates were removed.

if (FALSE) {
library(mapview)
mapview(sf_c14$geom)
}
