Hi ViviXiang,

Thanks for the question! Which version of Julia are you using? Alternatively, there might be a broken dependency in the DataFrames / NGSIM package.

The most up-to-date DataFrames has a different renaming function than the one NGSIM seems to call, according to julia wikibooks. It seems like it should be rename!(df, :old => :new) instead of rename!(df, :old, :new) at ngsim_trajdata.jl:37. The NGSIM package lives here: . Please start an issue there if we know it isn't ngsim_env specific.

Action items for you:

• Try changing line 37 as above and see if it solves your issue. Let me know if it does or does not.
• Open a new issue in the NGSIM repository with the result of your changes. Be sure to include your julia version.

CC: @MaximeBouton - does the above sound reasonable?

@djp42 Using rename!(df, :old => :new) instead of rename!(df, :old, :new) at [ngsim_trajdata.jl:37] really helps, thanks very much for your help.

Could you maybe submit a PR or restrict the version of dataframes?
