ess-r-insert-obj

Utilities to help inserting variable (column) names or values in ESS-R.

ESS-R has it own completing system, e.g., ess-r-complete-object-name and ess-r-get-rcompletions. For example, if dt is a data.frame, after the $ (dt$|), the completing list of variables in the data.frame will be prompted.

However, if we works with tidyverse, the completing system is not so helpful. This package provide the utilities to help completing names of data frame or variable values in a semi-automatic way.
