Create and validate well-known text

Like other geo types, geo_wkt() doesn't convert its input but does validate it using validate_geovctrs_wkt(). To skip validation, use new_geovctrs_wkt().

geo_wkt(x = character())

parse_wkt(x)

as_geo_wkt(x, ..., trim = TRUE, precision = 16, dimensions = 3)

Arguments

x	A character vector containing well-known text
...	Unused
trim	Trim unnecessary zeroes in the output?
precision	The rounding precision to use when writing (number of decimal places).
dimensions	The maximum number of dimensions to consider when generating text.

Value

A new_geovctrs_wkt()

Examples

# use geo_wkt() to "mark" a vector as well-known text
geo_wkt("POINT (30 10)")
#> <geovctrs_wkt[1]>
#> [1] POINT (30 10)

# use as_geo_wkt() to use conversion options
as_geo_wkt("POINT (30 10)", trim = FALSE, precision = 2)
#> <geovctrs_wkt[1]>
#> [1] POINT (30.00 10.00)

# use parse_wkt() to identify parsing failures
parse_wkt("POINT EMTPY")
#> Warning: 1 parsing failure.
