Helper function for mk_likertplot. Not for external use.

Description

prep_data_likert takes in the original data frame, the x, y and fillby variable, the supplied levels of the fillby variable, and instruction on how to order the y levels. It returns a list of 2 data frames (df_neg and df_pos), along with some plot elements for making a likert chart, a.k.a., horizontal diverging bar chart.

Usage

prep_data_likert(df, xvar, yvar, fillby, fillby_lvls, rawcnt_var, yorder)

Arguments

df	Data frame of the original data.
xvar	String, name of x numeric variable.
yvar	String, name of y categorical (character or factor) variable.
fillby	String, name of a second categorical variable for sub-dividing and coloring the bars.
fillby_lvls	Character vector, levels of the fillby variable that the fillby variable should be ordered accordingly.
yorder	String, possible values are "alphanumeric", "descend" or "ascend". If "alphanumeric", order y levels in alphanumerical order along y-axis. If "ascend"/"descend", order y levels in ascending/descending order of the sum of absolute x-values along y-axis.
rawcnt_var.	String, name of the variable that contains the raw count behind each tier. Default = NULL because not all input dataframe has such a variable.

Value

A list of 2 data frames (df_neg and df_pos), breaks and labels for the continuous axis, and palette for coloring the bars (pal).
