\title{Create point geometries from coordinate vectors}
\usage{
ddbs_point(
  x,
  y,
  z = NULL,
  m = NULL,
  ...,
  crs = NULL,
  geom_col = "geometry",
  conn = NULL,
  name = NULL,
  mode = NULL,
  overwrite = FALSE,
  quiet = FALSE
)
}
\arguments{
\item{x}{Numeric vector of X (longitude) coordinates.}

\item{y}{Numeric vector of Y (latitude) coordinates.}

\item{z}{Optional numeric vector of Z (elevation) coordinates.}

\item{m}{Optional numeric vector of M (measure) coordinates. Requires
\code{z}.}

\item{...}{Named vectors of additional attribute columns to include in the
output. Each must have the same length as \code{x}.}

\item{crs}{Character or numeric CRS specification (e.g. \code{"EPSG:4326"}
or \code{4326}). Defaults to \code{NULL} (no CRS assigned).}

\item{geom_col}{Name of the geometry column in the output. Defaults to
\code{"geometry"}.}

\item{conn}{A connection object to a DuckDB database. If \code{NULL}, the function
runs on a temporary DuckDB database.}

\item{name}{A character string of length one specifying the name of the table,
or a character string of length two specifying the schema and table
names. If \code{NULL} (the default), the function returns the result as an
\code{sf} object}

\item{mode}{Character. Controls the return type. Options:
\itemize{
\item \code{"duckspatial"} (default): Lazy spatial data frame backed by dbplyr/DuckDB
\item \code{"sf"}: Eagerly collected sf object (uses memory)
}
Can be set globally via \code{\link{ddbs_options}(mode = "...")} or
per-function via this argument. Per-function overrides global setting.}

\item{overwrite}{Boolean. whether to overwrite the existing table if it exists. Defaults
to \code{FALSE}. This argument is ignored when \code{name} is \code{NULL}.}

\item{quiet}{A logical value. If \code{TRUE}, suppresses any informational messages.
Defaults to \code{FALSE}.}
}
\value{
Depends on the \code{mode} argument (or global preference set by \code{\link{ddbs_options}}):
\itemize{
\item \code{duckspatial} (default): A \code{duckspatial_df} (lazy spatial data frame) backed by dbplyr/DuckDB.
\item \code{sf}: An eagerly collected object in R memory, that will return the same data type as the
\code{sf} equivalent (e.g. \code{sf} or \code{units} vector).
}
When \code{name} is provided, the result is also written as a table or view in DuckDB and the function returns \code{TRUE} (invisibly).

\description{
Constructs POINT geometries from numeric coordinate vectors, optionally
including Z (elevation) and M (measure) dimensions and extra attribute
columns.
