Find the numerical variable that skewed variable that inherits the data.frame or data.frame.

find_skewness(.data, index = TRUE, value = FALSE, thres = NULL)

Arguments

.data

a data.frame or a tbl_df.

index

logical. When representing the information of a skewed variable, specify whether or not the variable is represented by an index. Returns an index if TRUE or a variable names if FALSE.

value

logical. If TRUE, returns the skewness value in the individual variable.

thres

Returns a skewness threshold value that has an absolute skewness greater than thres. The default is NULL to ignore the threshold. but, If value = TRUE, default to 0.5.

Value

Information on variables including skewness.
