BUT in the python lessons, we used that species column name as a learning moment. We have the students do a \"join\" in pandas and given the species column is a duplicate name in both tables (but with different information) they get extra columns with different names as their output dataframe. they get species_x and species_y because pandas doesn't know what to do with the duplicate named columns.In my mind, this is a good way to teach the concept of why column names are important, reinforcing what was taught in the spreadsheet stuff. just my two cents - but this is something to consider. it seems there isn't a join function taught in the R lessons.\r\n\r\nhttps://github.com/datacarpentry/python-ecology/blob/gh-pages/04-merging-data.md"}}
