In this short article I introduce the stokes package which provides functionality for working with tensors, alternating forms, wedge products, and related concepts from the exterior calculus. Notation and spirit follow Spivak. Stokes's generalized integral theorem, viz $\int_{\partial X}\phi=\int_Xd\phi$, is demonstrated here using the package; it is available on CRAN athttps://CRAN.R-project.org/package=stokes.
