R Logical Vectors
R Logical Vector is an atomic vector whose type is “logical”. A logical value is either TRUE or FALSE. Logical vector items can have a value of NA as well.
In this tutorial, we will learn how to create a logical vector in R, with examples.
Allowed Values in Logical Vector
The following are the list of values allowed in a logical vector.
Create a Logical Vector using c()
To create a logical vector, we can use c() function.
In the following example, we create a logical vector with length 5. We print the type of vector, and the vector contents.
x <- c(TRUE, FALSE, FALSE, NA, TRUE, NA) print(typeof(x)) print(x)
1] "logical"  TRUE FALSE FALSE NA TRUE NA
Create Logical Vector from Comparisons
We can also create a logical vector from comparisons.
For example, we take a numeric vector, and check if the items are even.
In the following program, x is a numeric vector, and we check if its values are even using Equal-to
== comparison operator.
x <- c(2, 3, 7, 6, 1) result <- x%%2 == 0 print(result)
 TRUE FALSE FALSE TRUE FALSE
In this R Tutorial, we learned what logical vectors are, different values allowed in a logical vector, and how to create a logical vector, with the help of examples.
