diffobj - Diffs for R Objects
Generate a colorized diff of two R objects for an intuitive visualization of their differences.
See vignettes for details, and for comparisons with standard comparison functions.
Output
If your terminal supports formatting through ANSI escape sequences, diffobj will output colored diffs to the terminal. Otherwise, output will be colored with HTML/CSS and sent to the IDE viewport or to your browser. diffobj comes with several built-in color schemes that can be further customized. Some examples:
