> All file paths in R are wrapped in {{fs::path_abs()}}, which handles relative paths, but it doesn't expand {{~}}, so this fails:
> {code:java}
> > df <- read_parquet("~/Downloads/demofile.parquet")
>  Error in io___MemoryMappedFile__Open(fs::path_abs(path), mode) :
>    IOError: Failed to open local file '~/Downloads/demofile.parquet', error: No such file or directory
> {code}
> This is fixed by using {{fs::path_real()}} instead.
> Should this be properly handled in C++ though? cc [~pitrou]
