Description

This function plots a histogram (hst) on a given data frame, and uses simplified calls within the function to parse the histogram by up to 2 variables.

Usage

hst(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 histogram for var1 should be parsed.

by2

a potential second independent/predictor variable, X_2. A second grouping variable by which the histogram for var1 (already parsed by by1) should be parsed.

Value

This function returns the histogram for var1 in data frame df. Can be split to return a histogram for var1 in data frame df, broken out by var2.

Examples

data <- mtcars

hst(data,mpg,cyl)
