Check Atomic Vector Intersection

Checks that all the elements in atomic vector x intersect with those in atomic vector y.

check_intersection(
  x,
  y,
  all_y = FALSE,
  x_name = substitute(x),
  y_name = substitute(y),
  error = TRUE
)

Arguments

x

The object to check.

y

The second atomic vector.

all_y

A flag indicating whether all the elements in y should have a match in x.

x_name

A string of the name of the object x.

y_name

A string of the name of the object y.

error

A flag indicating whether to throw an informative error or immediately generate an informative message if the check fails.

Value

An invisible copy of x (if it doesn't throw an error).
