diffviewer

diffviewer provides an HTML widget for visually comparing files. It currently wraps three javascript libraries:

• resemble.js for comparing images.
• daff.js for comparing data frames.
• jsdiff for everything else.

It extracts out common UI provided by shinytest and vdiffr.

Installation

You can install the released version of diffviewer from CRAN with:

install.packages("diffviewer")

Example

This is a basic example which shows you how to solve a common problem:

library(diffviewer)
path1 <- tempfile()
writeLines(letters, path1)
path2 <- tempfile()
writeLines(letters[-(10:11)], path2)

visual_diff(path1, path2)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
