As mentioned in the title, I would like to select a column with name "Avg Estimates" in a dataframe. How can I do this by using "$" operator? Thank you!

9In fact, backticks (\`), single quotes ('), and double quotes (") can all be used. Other options include `'$'(df, 'Avg Estimates')`, `df[['Avg Estimates']]`, and `'[['(df, 'Avg Estimates')`, and `get('Avg Estimates', df)` – Benjamin Jan 06 '16 at 20:34
