Diff Two Vectors

A convenient diff tool to determine how and where two character vectors differ.

Usage

diff_vecs(x, y, verbose = interactive())

Arguments

x

character(n). First vector to compare.

y

character(n). Second vector to compare.

verbose

logical(1). Should diff summary be printed directly to the console? Is TRUE for interactive sessions.

Value

An invisible list is returned with the set diffs of each vector. The elements of the list are:

unique_x:

Entries unique to x.

unique_y:

Entries unique to y.

inter:

The intersect x and y.

unique:

The union() of x and y.

Examples

diff_vecs(LETTERS[1:10L], LETTERS[5:15L])

diffs <- diff_vecs(LETTERS[1:10L], LETTERS[5:15L], verbose = FALSE)
