This function, and those specified below in 'See Also', work best when used
inside a call to dplyr's mutate() for creating new variables.
The point of the function is to make it easy to use regular expressions to
select variables for aggregation, such as an average score for a number of
questionnaire items or the sum of correct responses.
See Also
average_rows for row averaging across rows, sum_missings for summing
missing values, and sd_rows for calculating standard deviations across rows.
