R can perform the usual mathematical operations, below are the functions:


  • +    – addition
  •     – subtraction
  • *    – multiplication
  • /    – division


  • sin      – sine
  • cos      – cosine
  • tan      – tangent
  • asin    – sine inverse
  • acos    – cosine inverse
  • atan    – tangent inverse

Linear Algebra

  • +            – element-wise addition
  •             – element-wise subtraction
  • *            – element-wise multiplication
  • /            – element-wise division
  • %*%        – matrix multiplication
  • t            – transpose
  • eigen    – eigenvalues and eigenvectors
  • solve    – inverse of matrix
  • ginv      – generalized inverse, requires MASS package
  • rbind    – combines vectors of observations horizontally into matrix class
  • cbind    – combines vectors of observations vertically into matrix class
