wtd.sd

This function calculates standard deviations with weights and
is a counterpart to the built-in <code>weighted.mean</code> function.

This is a collection of tools for more efficiently understanding
and sharing the results of (primarily) regression analyses. There are also a
number of miscellaneous functions for statistical and programming purposes.
Support for models produced by the survey and lme4 packages are points of
emphasis.
