name elements in vector r
Naming Elements in a Vector in R
To name elements in a vector in R, you can use the names()
function. Here's an example of how to do it:
# Create a vector
r <- c(1, 2, 3, 4, 5)
# Assign names to the vector elements
names(r) <- c("a", "b", "c", "d", "e")
In this example, we create a vector r
with elements 1, 2, 3, 4, and 5. Then, we use the names()
function to assign names to each element of the vector. The names are specified as a character vector c("a", "b", "c", "d", "e")
. After assigning the names, the vector r
will have named elements.
The resulting vector r
with named elements will look like this:
a b c d e
1 2 3 4 5
Now you can refer to the elements of the vector using their names. For example, r["a"]
will give you the value 1.
