completejourney 1.1.0

New features

• Added an internet check with curl::has_internet() and condition handling to
  provide informative error when downloading online data sets.

Bug fixes

• Removed ^data$ from .Rbuildignore and only specified ignoring the .rds
  files. This resolved issue (#14).
  As a consequence, the package was too large now that the build included the
  required data sets so I downsampled the transactions_sample and
  promotions_sample data sets.
