Measures of symmetry

Returns the measures of symmetry such as skewness and kurtosis.

ds_measures_symmetry(data, ..., decimals = 2)

Arguments

data	A data.frame or tibble.
...	Column(s) in data.
decimals	An option to specify the exact number of decimal places to use. The default number of decimal places is 2.
