Changes in version 1.7.5.9000                      

Fixed

  - metric_PPMC(): added use = "pairwise.complete.obs" to stats::cor()
    so the Pearson correlation is computed on available pairs rather
    than returning NA whenever any observation is missing. This matches
    the behaviour of metric_cor() in the same package.

  - Improved clarity of code examples that are not run at check time.

                        Changes in version 1.7.5                        

  - Added keywords and bug reporting URL to DESCRIPTION.
  - No code changes in this release.

                        Changes in version 1.7.4                        

  - Removed Browndog support
  - Documentation fixes
