Added option neverTreatedValue(), which allows the user to specify a value of the variable g which denotes that an observation is never treated. This option can take either a numeric value or a period to denote that missing values indicate that an observation was never treated. There is also now a warning if Rcall version 3.0 or greater is used, and we now drop any missing values of g not addressed by neverTreatedValue() prior to passing the data to R.
