# diffobj - Diffs for R Objects
[](https://github.com/brodieG/diffobj/actions)
[](https://codecov.io/github/brodieG/diffobj?branch=master)
[](https://cran.r-project.org/package=diffobj)
[](https://tinyverse.netlify.app/)
Generate a colorized diff of two R objects for an intuitive visualization of their differences.
> See the [introductory vignette for details][1].
## 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:
## Installation
This package is available on [CRAN](https://cran.r-project.org/package=diffobj).
```
install.packages("diffobj")
browseVignettes("diffobj")
```

* [Daff](https://cran.r-project.org/package=daff) diff, patch and merge for
data.frames.
* [GNU diff](https://www.gnu.org/software/diffutils/).
* [waldo](https://cran.r-project.org/package=waldo), which internally uses
`diffobj` for diffs but takes a more hands-on approach to detailing object
differences.
