katilingban/ennet: ennet v0.2.0

Second CRAN release of ennet package.

• Fixed NOTE on CRAN checks for non-ASCII characters (192 marked UTF-8 strings)

• Removed DiagrammeR as a dependency package and removed the code chunk in respective vignette that creates the ennet workflow. The workflow diagram is now done using an external drawing tool (OmniGraffle) instead of within R using DiagrammeR. This prevents issues on CRAN when vignettes are produced.

• refactored the count_topics and count_authors functions into new more coherent functions for counting topics and other related metrics (previous functions have now been deprecated);

• added new functions to retrieve data from the en-net database;

• added new functions to process and handle data from the en-net database; and,

• updated documentation to reflect the enhancements/improvements implemented.
