qdap Version 2.0.0

Initial 2.0.0 bump:

CHANGES IN qdap VERSION 2.0.0

The qdapTools package now houses several former qdap functions. While
qdapTools is a Dependency and all of these functions will be accessible to
the qdap user there is a break in backward compatability if these functions
are included in code. For this reason this release is a major bump of qdap.

CHANGES

• The qdapTools package now houses the following former qdap functions:
  hash, %ha%, hash_look, hms2sec, id, lookup, %l%, %l+%, %l*%,
  repo2github, sec2hms, text2color, url_dl, v_outer. These functions
  will continue to be available to qdap users in interactive mode (qdapTools
  is a Dependency and thus these functions are loaded into the workspace by
  default). This will allow this bundle of functions to be used outside of
  qdap without calling the larger qdap package per the request of Kirill Muller
  (see issue #165).
• The dissimialrity function has been removed from the qdap package to avoid
  conflict with the tm package. Use Dissimilarity function instead.
