[R] Expand file paths when passing to readers

    XMLWordPrintableJSON

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 0.15.0
    • Component/s: R

      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]
