Convert a c14_date_list to a sf object

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.

Usage

as.sf(x, quiet = FALSE)

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

# S3 method for class '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

sf_c14 <- as.sf(example_c14_date_list)
#> Warning: Dates without coordinates were removed.

if (FALSE) { # \dontrun{
library(mapview)
mapview(sf_c14$geom)
} # }
