Visualize by attribute of `pps` class. The plot of a PPS(Predictive Power Score) is a bar plot or tile plot by PPS.
# S3 method for pps
plot(x, typographic = TRUE, base_family = NULL, ...)Arguments
- x
an object of class "pps", usually, a result of a call to pps().
- typographic
logical. Whether to apply focuses on typographic elements to ggplot2 visualization. The default is TRUE. if TRUE provides a base theme that focuses on typographic elements using hrbrthemes package.
- base_family
character. The name of the base font family to use for the visualization. If not specified, the font defined in dlookr is applied. (See details)
- ...
arguments to be passed to methods, such as graphical parameters (see par).
Value
A ggplot2 object.
Details
The base_family is selected from "Roboto Condensed", "Liberation Sans Narrow", "NanumSquare", "Noto Sans Korean". If you want to use a different font, use it after loading the Google font with import_google_font().
