Use “NOT IN” with Vectors
Here we are going to use this operator in a vector to select the elements that are not in particular elements.
Syntax:
vector[!(vector %in% c(values))]
where,
- vector is an input vector
- values are the values to be checked
Example:
R
# vector vector1 = c(23, 34, 56, 23, 16, 78, 56, 4, 5, 6, 7, 8) # display print(vector1) # get the elements from a vector not in the values print(vector1[!(vector1 % in % c(23, 34, 56, 5, 6, 7))]) |
Output:
[1] 23 34 56 23 16 78 56 4 5 6 7 8 [1] 16 78 4 8
How to Use “NOT IN” Operator in R?
In this article, we will discuss NOT IN Operator in R Programming Language.
NOT IN Operator is used to check whether the element in present or not. The symbol used for IN operator is “%in%”. For NOT IN operator we have to add ” ! ” operator before that , so the symbol for NOT IN operator is “! %in%”.
