Added RSqDelta(), SCorDelta(), PCorDelta(), DeltaRSqDelta(), and FSqDelta(): delta-method intervals for R-squared and adjusted R-squared, semipartial correlations, squared partial correlations, the improvement in R-squared, and Cohen’s f-squared (global and local), with normal-theory or ADF standard errors, as in betaMC and betaNB.
The new functions and DiffBetaDelta() return objects of class esdelta with one set of methods. DiffBetaDelta() objects also keep the class diffbetadelta.

Selective standardization: the arguments std_y and std_x standardize only y or only the named regressors (for example, leave a dummy variable in its 0-1 units). The defaults give the same results as before.
DiffBetaDelta() stops when the slopes are not fully standardized.
