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.
