  The Dip Test of Unimodality and Silverman's Critical Bandwidth Test are two
popular tests to determine if an unknown density contains more than one mode.
While the tests can be easily run in R, they are not included in SAS software.
We provide implementations of the Dip Test and Silverman Test as macros in the
SAS software, capitalizing on the capability of SAS to execute R code
internally. Descriptions of the macro parameters, installation steps, and
sample macro calls are provided, along with an appendix for troubleshooting. We
illustrate the use of the macros on data simulated from one or more Gaussian
distributions as well as on the famous $\textit{iris}$ dataset.
