writeVector.Rd
Write a SpatVector to a file. You can choose one of many file formats.
# S4 method for SpatVector,character
writeVector(x, filename, filetype=NULL, layer=NULL, insert=FALSE,
overwrite=FALSE, options="ENCODING=UTF-8")
SpatVector
character. Output filename
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
character. Output layer name. If NULL
the filename is used
logical. If TRUE
, a new layer is inserted into the file, if the format allows it (e.g. GPKG allows that). See vector_layers
to remove a layer
logical. If TRUE
, filename
is overwritten
character. Format specific GDAL options such as "ENCODING=UTF-8". Use NULL or "" to not use any options
