diffobj: Compare two dfs (or other objects)

What’s the difference between two dfs?

diffobj::diffPrint() gives a handy visual way to check differences:

library(diffobj)

a <- b <- matrix(1:100, ncol=2)
a <- a[-20,]
b <- b[-45,]
b[c(18, 44)] <- 999

diffPrint(target=a, current=b)

< a                > b

(In RStudio, this is shown in a colorful manner in the Viewer)

This also works for other types of objects, such as character vectors:

diffPrint(letters[1:3], c("a", "B", "c"))

< letters[1:3]     > c("a", "B", "..
@@ 1 @@            @@ 1 @@          
< [1] "a" "b" "c"  > [1] "a" "B" "c"
