Spatial - Exports a data frame object.

Description

Exports a data frame object to a specified output.

Usage

datExportData(
  dfobj,
  create_dsn = FALSE,
  index.unique = NULL,
  index = NULL,
  savedata_opts = savedata_options(),
  dbconn = NULL,
  dbconnopen = FALSE
)

Arguments

dfobj	Data.frame class R object. Data frame object to export.
create_dsn	Boolean.
index.unique	String. Name of variable(s) in dfobj to make unique index.
index	String. Name of variable(s) in dfobj to make (non-unique) index. dbconnopen Logical. If TRUE, keep database connection open.
savedata_opts	List. See help(savedata_options()) for a list of options.
dbconn	Open database connection.

Details

Wrapper for sf::st_write function.

Value

An sf spatial object is written to the out_dsn.

Note

If out_fmt='shp':
The ESRI shapefile driver truncates variable names to 10 characters or less. Variable names are changed before export using an internal function (trunc10shp). Name changes are output to the outfolder, 'outshpnm'_newnames.csv.

If sf object has more than 1 record, it cannot be exported to a shapefile.
