deleteDataset: Delete named dataset

In gdalraster: Bindings to 'GDAL'

Delete named dataset

Description

deleteDataset() will attempt to delete the named dataset in a format specific fashion. Full featured drivers will delete all associated files, database objects, or whatever is appropriate. The default behavior when no format specific behavior is provided is to attempt to delete all the files that would be returned by GDALRaster$getFileList() on the dataset. The named dataset should not be open in any existing GDALRaster objects when deleteDataset() is called. Wrapper for GDALDeleteDataset() in the GDAL API.

Usage

deleteDataset(filename, format = "")

Arguments

filename	Filename to delete (should not be open in a GDALRaster object).
format	Raster format short name (e.g., "GTiff"). If set to empty string "" (the default), will attempt to guess the raster format from 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 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

b5_file <- system.file("extdata/sr_b5_20200829.tif", package="gdalraster")
b5_tmp <- file.path(tempdir(), "b5_tmp.tif")
file.copy(b5_file,  b5_tmp)

ds <- new(GDALRaster, b5_tmp)
ds$buildOverviews("BILINEAR", levels = c(2, 4, 8), bands = c(1))
files <- ds$getFileList()
print(files)
ds$close()
file.exists(files)
deleteDataset(b5_tmp)
file.exists(files)
