Getting and Setting Length of the Vectors in R Programming – length() Function
length() function in R Language is used to get or set the length of a vector (list) or other objects.
Syntax: length(x)
Parameters:
x: vector or object
Example 1:
Python3
# R program to illustrate# length function# Specifying some vectorsx <- c(6)y <- c(1, 2, 3, 4, 5)# Calling length() function# to get length of the vectorslength(x)length(y) |
Output :
[1] 1 [1] 5
Example 2:
Python3
# R program to illustrate# length function# Specifying some vectorsx <- c(3)y <- c(1, 2, 3, 4, 5)z <- c(1, 2, 3, 4, 5)# Setting length of the vectorlength(x) <- 2length(y) <- 7length(z) <- 3# Getting elements of the# new vectorsxyz |
Output:
[1] 3 NA [1] 1 2 3 4 5 NA NA [1] 1 2 3
