title: 'ricci: Ricci Calculus'
version: 0.1.1.9000
doi: 10.32614/CRAN.package.ricci
abstract: Provides a compact 'R' interface for performing tensor calculations. This
  is achieved by allowing (upper and lower) index labeling of arrays and making use
  of Ricci calculus conventions to implicitly trigger contractions and diagonal subsetting.
  Explicit tensor operations, such as addition, subtraction and multiplication of
  tensors via the standard operators, raising and lowering indices, taking symmetric
  or antisymmetric tensor parts, as well as the Kronecker product are available. Common
  tensors like the Kronecker delta, Levi Civita epsilon, certain metric tensors, the
  Christoffel symbols, the Riemann as well as Ricci tensors are provided. The covariant
  derivative of tensor fields with respect to any metric tensor can be evaluated.
  An effort was made to provide the user with useful error messages.
