top_levels

Get a frequency table of a factor variable, grouped into categories by level.

The main janitor functions can: perfectly format data.frame column
names; provide quick counts of variable combinations (i.e., frequency
tables and crosstabs); and explore duplicate records. Other janitor functions
nicely format the tabulation results. These tabulate-and-report functions
approximate popular features of SPSS and Microsoft Excel. This package
follows the principles of the "tidyverse" and works well with the pipe function
%>%. janitor was built with beginning-to-intermediate R users in mind and is
optimized for user-friendliness.
