1 2	ttestIS(data, dependent, grouping, alternative = "two.sided", mu = 0, varEqual = FALSE, confLevel = 0.95)

`data`	the data as a data frame
`dependent`	a string specifying the dependent variable in `data`
`grouping`	a string specifying the grouping variable in `data`; must have two levels
`alternative`	`'two.sided'`, `'less'`, or `'greater'`
