Description: Provides tools for working with Type S (Sign) and Type M
        (Magnitude) errors, as proposed in Gelman and Tuerlinckx (2000)
        <doi:10.1007/s001800000040> and Gelman & Carlin (2014)
        <doi:10.1177/1745691614551642>. In addition to simply
        calculating the probability of Type S/M error, the package
        includes functions for calculating these errors across a
        variety of effect sizes for comparison, and recommended sample
        size given "tolerances" for Type S/M errors. To improve the
        speed of these calculations, closed forms solutions for the
        probability of a Type S/M error from Lu, Qiu, and Deng (2018)
        <doi:10.1111/bmsp.12132> are implemented. As of 1.0.0, this
        includes support only for simple research designs. See the
        package vignette for a fuller exposition on how Type S/M errors
        arise in research, and how to analyze them using the type of
        design analysis proposed in the above papers.
