the R-packages text 1.6 and topics .6 are now on CRAN
topics includes visualisation improvements
text is now easier to install, it checks for dependencies and instructs how to install them
hope to get more user feedback to improve installation further

1/ Correction! 🚨 I found and fixed an important coding error in a chart I made.
Specifically, the peach category 'lymphatic and blood cancers' in this chart wrongly included both lymphoid and blood cancers (C81-C96) plus some of its subcategories, meaning some were double-counted.
