copyDatasetFiles() copies all the files associated with a dataset. Wrapper for GDALCopyDatasetFiles() in the GDAL API.

Usage

copyDatasetFiles(new_filename, old_filename, format = "")

Arguments

new_filename

New name for the dataset (copied to).

old_filename

Old name for the dataset (copied from).

format

Raster format short name (e.g., "GTiff"). If set to empty string "" (the default), will attempt to guess the raster format from old_filename.

Value

Logical TRUE if no error or FALSE on failure.

Note

If format is set to an empty string "" (the default) then the function will try to identify the driver from old_filename. This is done internally in GDAL by invoking the Identify method of each registered GDALDriver in turn. The first driver that successful identifies the file name will be returned. An error is raised if a format cannot be determined from the passed file name.

Examples

lcp_file <- system.file("extdata/storm_lake.lcp", package="gdalraster")
ds <- new(GDALRaster, lcp_file)
ds$getFileList()
#> [1] "/home/runner/work/_temp/Library/gdalraster/extdata/storm_lake.lcp"
#> [2] "/home/runner/work/_temp/Library/gdalraster/extdata/storm_lake.prj"
ds$close()

lcp_tmp <- file.path(tempdir(), "storm_lake_copy.lcp")
copyDatasetFiles(lcp_tmp, lcp_file)
#> [1] TRUE
ds_copy <- new(GDALRaster, lcp_tmp)
ds_copy$getFileList()
#> [1] "/tmp/Rtmpi7gt4V/storm_lake_copy.lcp" "/tmp/Rtmpi7gt4V/storm_lake_copy.prj"
ds_copy$close()

deleteDataset(lcp_tmp)
#> [1] TRUE
