RData. UndefVarError: identifier not defined


got the error:

UndefVarError: identifier not defined

Also, when loading the package RData I got:
WARNING: could not import DataFrames.identifier into RData

How to fix this?

Julia Version 1.4.1

Isn’t the extension .rda rather than .RData?

The fix to this is already on RData.jl master, so just install this version and all should work fine. The problem is that RData.jl version containing this fix has not been released yet.
