Compress an object of class mytable

You can compress mytable. If rows dealing with categorical variables have two unique values, it can be printed in a single row rather than three rows.

For formatted numbers: addComma()

Sometimes, you want to display formatted numbers. For example, 1234.5 can be printed as 1,234.5. You can do this using addComma() function

data(diamonds,package="ggplot2")
mytable(diamonds) %>% addComma
