In interactive mode, ask users for permission to create a .sen2r settings directory, in which to store files required by the packages. The function can be used also in non-interactive mode by setting agree = TRUE. The function has no effect if the directory already exists.

give_write_permission(agree = NA)

Arguments

agree

Logical: if TRUE, allow creating the hidden directory; if FALSE, do not allow it; if NA (default), the permission is asked to the user in interactive mode (in non-interactive mode, the permission is denied).

Value

Logical: if TRUE, R was authorised saving in the directory; if FALSE, it was not and a temporary directory is being used.
