How to rename a column to a variable name “in a tidyverse way”

Question

I\'ve created a simple data frame (dput below):

    date      ticker     value
------------------------------
  2016-06-30  A2M.ASX   0.0686
  2

With the newest dplyr (>0.7.0) you would use

rename(df, !!metric:=value)

The syntax is "new_name=old_name" and you need to use := with !! to put a variable on the left side of a parameter name.
