r-cran-tibble 3.1.8+dfsg-1 (s390x binary) in ubuntu kinetic

 This GNU R package provides a 'tbl_df' class that offers better checking
 and printing capabilities than traditional data frames.
 .
 Tibbles are a modern take on data frames. They keep the features that have
 stood the test of time, and drop the features that used to be convenient but
 are now frustrating (i.e. converting character vectors to factors).
