    args: &[RValue],
    named: &[(String, RValue)],
    context: &BuiltinContext<'_>,
) -> Result<RValue, RError>

Random inverse Gaussian (Wald) deviates.

miniR extension – not available in base R.

The inverse Gaussian distribution is a continuous distribution defined for x > 0, parameterised by mean mu and shape lambda.

@param n number of observations @param mu mean parameter (positive) @param lambda shape parameter (positive) @return numeric vector of length n
