Version 1.0-8 (2015-08-29)
  + Add kappaLA and kappaSimp to calculate kappa statistics; benchmark remains to be done to determine which one works better
  + Add testthat tests for kappaLA and kappaSimp
  
Version 1.0-4 (2013-03-06)
  + cossim works now with y missing.

Version 1.0-3 (2013-02-27)
  + Removing package dependence on Rcpp: so far the package is placed under "LinkingTo" it runs fine.

Version 1.0-2 (2013-02-26)
  + Add function empval to calculate empirical p values from Monte Carlo methods
  + Add function randmat to generate a column-wise random matrix by sampling a numeric vector many times

Version 1.0-1 (2013-02-25)
  + cossim and cosdist have been updated to work with matrices. Using matrix manipulation much accelerates the calculation.

Version 1.0-0 (2013-02-22)
  + New package ribiosMath for mathematic and statistical functions in ribios
  + Add function cossim for cosine similarity
  + Add function cosdist for cosine distance
