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.
You can install the released version of diffviewer from CRAN with:
install.packages("diffviewer")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)
