x %==% y

x %!=% y

x, y

two data structures

base::identical() function tests for an exact match meaning that the variable's storage types match, the overall environment the variable is stored in is the same, and, most importantly, there is no tolerance for small numerical differences.

When in doubt, consult base::all.equal() to perform near equality tests using a tolerance operation (e.g does a number fall within a certain range). However, the use of base::all.equal() must be enclosed within base::isTRUE() as the function is setup to return differences.

base::identical()

# Generate some data
set.seed(991)
x = y = rnorm(100)

# Returns TRUE as the objects are exactly the same
x %==% y

# Returns FALSE as the objects do not differ.
x %!=% y

# Change data
x2 = x+1

# Returns FALSE as the data has changed.
x2 %==% y

# Returns TRUE since the data is different.
x2 %!=% y
