Write SpatVector data to a file
writeVector.Rd
Write a SpatVector to a file. You can choose one of many file formats.
Usage
# S4 method for class '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. IfNULL
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, if the format allows it (e.g. GPKG allows that). Seevector_layers
to remove a layer- overwrite
logical. If
TRUE
,filename
is overwritten- 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)
