`y_name`	A character value, the column name of the response variable, the default is NULL.
`mu`	An numeric value specifying the median
`alternative`	The type of hypothesis being tested; two.sided, greater, less. The default is "two.sided"

#-- Example Lung Capcity Data --#

# Perform Wilicoxon tests on the entire dataset
tests_wilcoxon(dataset = lungcap)

# Perform Wilicon=xon tests in relation to the second column.
tests_wilcoxon(dataset = lungcap, y_index = 2)

# Perform Wilcoxon tests in relation to the 'Age' Column.
tests_wilcoxon(dataset = lungcap, y_name = "Age")
