read_rda

✓ from rdata import read_rda

✗ from rdata.parser import read_rda

read_rda is exposed at top-level, not in parser submodule.

Open an .rda file in binary mode and parse with read_rda. Returns a dict of R objects.

from rdata import read_rda import os # Replace with your .rda file path file_path = os.environ.get('RDATA_FILE', 'data.rda') with open(file_path, 'rb') as f: data = read_rda(f) print(data)

Debug

Known issues

breakingRequires Python >=3.11; will fail on older Python versions.

fix

Upgrade Python to 3.11 or later.

affects: 1.0.0

gotcharead_rda expects a binary file-like object, not a file path. Passing a string path raises TypeError.

fix

Open the file with open(path, 'rb') before calling read_rda.

affects: all

deprecatedThe function 'read_r' from older versions (pre-0.2) is deprecated; use read_rda instead.

fix

Replace read_r with read_rda and adjust argument order.

affects: <1.0.0

Errors

Common errors & fixes

TypeError: expected str, bytes or os.PathLike object, not bytes

Passing a path string directly to read_rda instead of a file object.

fix

Use open('file.rda', 'rb') to create a file object.

rdata._parser.RDataParserError: invalid file signature

File is not a valid .rda file or is corrupted.

fix

Verify the file is an R data file; re-save from R if needed.
