Check if Elements Are Not in a Vector

Source: R/not_in.r
grapes-not_in-grapes.Rd

[Deprecated]

%not_in% has been deprecated because base R (>= 4.6.0) now provides the %notin% operator.

Please use %notin% from base instead.

Usage

x %not_in% y

Arguments

x

A vector of values to be checked.

y

A vector of values to check against.

Value

A logical vector of the same length as x, where TRUE indicates the corresponding element in x is not found in y, and FALSE indicates it is found in y.

Examples


# Example vectors
x <- c("apple", "banana", "cherry")
y <- c("banana", "grape")

# Check which elements in `x` are not in `y`
x %not_in% y
#> Warning: `%not_in%()` was deprecated in traumar 1.2.7.
#> ℹ Please use `base::%notin%()` instead.
#> ℹ `base` R includes the %notin% operator as of R >= 4.6.0.
#> [1]  TRUE FALSE  TRUE

# Example with numeric values

b <- c(2, 4, 6)

a %not_in% b
#> [1]  TRUE FALSE  TRUE FALSE  TRUE
