Create boxplots with ggplot2.
bboxplot(y, ...) # S3 method for default bboxplot(y, g, data, ...) # S3 method for formula bboxplot(formula, data, ...)
| y | a numeric variable for which the boxplot is to be constructed.  | 
    
|---|---|
| ... | further arguments passed to   | 
    
| g | a grouping variable, usually a factor, for constructing parallel boxplots.  | 
    
| data | a dataframe containing the variables.  | 
    
| formula | A model formula of the form ~ y to produce a boxplot for the variable y, or of the form y ~ g to produce parallel boxplots for y within levels of the grouping variable(s) g, etc., usually factors.  | 
    
A boxplot of the variable y or the boxplot of the y
  against g.
