GISWrappers for GDAL Utilities Executables
Rs sf package ships with self-contained GDAL
executables, including a bare bones interface to several
GDAL-related utility programs collectively known as the GDAL
utilities. For each of those utilities, this package provides an
R wrapper whose formal arguments closely mirror those of the
GDAL command line interface. The utilities operate on data
stored in files and typically write their output to other
files. Therefore, to process data stored in any of Rs more common
spatial formats (i.e. those supported by the sf and terra
packages), first write them to disk, then process them with the
package's wrapper functions before reading the outputted results
back into R. GDAL function arguments introduced in GDAL version
3.5.2 or earlier are supported.

Including function calls in error messages — topic-error-call
Starting with rlang 1.0, abort() includes the erroring function in the message by default:
my_function <- function() {
abort("Can't do that.")
}
my_function()
#> Error in `my_function()`:
#> ! Can't do that.
This works well when abort() is called directly within the failing function. However, when the abort() call is exported to another function (which we call an "error helper"), we need to be explicit about which function abort() is throwing an error for.
This works well when abort() is called directly within the failing function. However, when the abort() call is exported to another function (which we call an "error helper"), we need to be explicit about which function abort() is throwing an error for.
There are two main kinds of error helpers:
Simple abort() wrappers. These often aim at adding classes and attributes to an error condition in a structured way:
stop_my_class <- function(message) {
abort(message, class = "my_class")
}
Input checking functions. An input checker is typically passed an input and an argument name. It throws an error if the input doesn't conform to expectations:
check_string <- function(x, arg = "x") {
if (!is_string(x)) {
cli::cli_abort("{.arg {arg}} must be a string.")
}
}
To fix this, let abort() know about the function that it is throwing the error for by passing the corresponding function environment as the call argument:
