I'm very happy that someone is interested in my new package, but I must worry you, that Grubbs test is probably not proper in such case. Your data are dependent (time series) and possibly autocorrelated. The outliers package is designed for testing small independent samples (for example results of quantitative chemical analysis), not time series data.
