writeVector: Write SpatVector data to a file

writeVectorR Documentation

Write SpatVector data to a file

Description

Write a SpatVector to a file. You can choose one of many file formats.

Usage

## S4 method for signature 'SpatVector,character'
writeVector(x, filename, filetype=NULL, layer=NULL, insert=FALSE,
    overwrite=FALSE, options="ENCODING=UTF-8")

Arguments

x

SpatVector

filename

character. Output filename

filetype

character. A file format associated with a GDAL "driver" such as "ESRI Shapefile". See gdal(drivers=TRUE) or the GDAL docs. If NULL it is attempted to guess the filetype from the filename extension

layer

character. Output layer name. If NULL the filename is used

insert

logical. If TRUE, a new layer is inserted into the file, or an existing layer overwritten (if overwrite=TRUE), if the format supports it (e.g. GPKG allows that). See vector_layers to remove a layer

overwrite

logical. If TRUE and insert=FALSE, filename is overwritten if the file format and layer structure permits it. If TRUE and insert=TRUE, only the target layer is overwritten if the format supports it (e.g. GPKG).

options

character. Format specific GDAL options such as "ENCODING=UTF-8". Use NULL or "" to not use any options

Examples

v <- vect(cbind(1:5,1:5))
crs(v) <- "+proj=longlat +datum=WGS84"
v$id <- 1:length(v)
v$name <- letters[1:length(v)]
tmpf1 <- paste0(tempfile(), ".gpkg")
writeVector(v, tmpf1, overwrite=TRUE)
x <- vect(tmpf1)

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
tmpf2 <- paste0(tempfile(), ".gpkg")
writeVector(v, tmpf2, overwrite=TRUE)
y <- vect(tmpf2)
