Description

All file paths in R are wrapped in fs::path_abs(), which handles relative paths, but it doesn't expand ~, so this fails:

> 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

This is fixed by using fs::path_real() instead.

Should this be properly handled in C++ though? cc pitrou
