r-cran-formatr 1.5-3 (amd64 binary) in ubuntu cosmic

 The GNU R package formatr provides a function tidy_source() to format R
 source code. Spaces and indent will be added to the code automatically,
 and comments will be preserved under certain conditions, so that R code
 will be more human-readable and tidy. There is also a Shiny app as a user
 interface in this package (see tidy_app()).
