This function plots a Box-and-Whisker (box) on a given data frame, and uses simplified calls within the function to parse the boxplot by up to 2 variables.
Usage
box(df, var1, by1, by2)
Arguments
df
data frame to read in.
var1
the dependent/outcome variable, \(Y\). The variable of interest that should be plotted.
by1
the main independent/predictor variable, \(X_1\). A grouping variable by which the boxplot for var1 should be parsed.
by2
a potential second independent/predictor variable, \(X_2\). A second grouping variable by which the boxplot for var1 (already parsed by by1) should be parsed.
