f_text_bar: Format Text Based Bar Plots

Description

Use a text symbol to create scaled horizontal bar plots of numeric vectors. Note that you will have to coerce the table to a data.frame in order for the output to look pretty.

Usage

f_text_bar(x, symbol = "_", width = 9, ...)
ff_text_bar(...)

Arguments

x

A numeric vector.

symbol

A sumbol to use for the bars.

width

The max width of the bar.

…

ignored.

Value

Returns a vector of concatenated symbols as a string that represent x
