Create a frequency table of a vector with items or a data frame. Supports quasiquotation and markdown for reports. \code{top_freq} can be used to get the top/bottom \emph{n} items of a frequency table, with counts as names.
Create a frequency table of a vector with items or a data frame. Supports quasiquotation and markdown for reports. The best practice is: \code{data \%>\% freq(var)}.\cr
\code{top_freq} can be used to get the top/bottom \emph{n} items of a frequency table, with counts as names.

\details{
Frequency tables (or frequency distributions) are summaries of the distribution of values in a sample. With the `freq` function, you can create univariate frequency tables. Multiple variables will be pasted into one variable, so it forces a univariate distribution. This package also has a vignette available to explain the use of this function further, run \code{browseVignettes("AMR")} to read it.
