y2clerk exists to quickly create formatted frequencies tables. It
leverages the tidyverse, allowing the user to %>% in data frames,
select() down to lists of variables, group_by() others, and include
weights for the frequencies. There are two main functions in y2clerk:
freqs()- creates a frequency table including both ns and percentages for each level of a variable or list of variables.freqs()is flexible and can also be used for calculating means, medians, or other quartiles while including weighting variables.verbatims_y2()- creates a table with similar formatting to freqs. However, this function is used for string variables and creates a table with all responses given.cross_freqs()- creates a frequency table similar to cross tabs. Each group_var given in the function acts as its own unique banner for every variable listed in the freqs. Whereas group_by %>% freqs produces a set of frequencies grouped by a single variable, cross_freqs is designed to produce a set of frequencies grouped by multiple different grouping variables one after another and then combines these results into a single dataframe.
You can install the most updated package version from GitHub with:
# install.packages("devtools")
devtools::install_github("y2analytics/y2clerk")Below you will find a few basic examples which show you how to quickly
get a frequencies table with freqs():
