Description

Return Well-known Text representation of simple feature geometry or coordinate reference system

Usage

# S3 method for crs
st_as_text(x, ..., pretty = FALSE)

st_as_text(x, ...)

# S3 method for sfg st_as_text(x, ...)

# S3 method for sfc st_as_text(x, ..., EWKT = FALSE)

Arguments

x

object of class sfg, sfc or crs

...

modifiers; in particular digits can be passed to control the number of digits used

pretty

logical; if TRUE, print human-readable well-known-text representation of a coordinate reference system

EWKT

logical; if TRUE, print SRID=xxx; before the WKT string if epsg is available

Examples

Run this code
# NOT RUN {
st_as_text(st_point(1:2))
st_as_text(st_sfc(st_point(c(-90,40)), crs = 4326), EWKT = TRUE)
# }
