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 vectors x < - c( 6 ) y < - c( 1 , 2 , 3 , 4 , 5 ) # Calling length() function # to get length of the vectors length(x) length(y) |
Output :
[1] 1 [1] 5
Example 2:
Python3
# R program to illustrate # length function # Specifying some vectors x < - c( 3 ) y < - c( 1 , 2 , 3 , 4 , 5 ) z < - c( 1 , 2 , 3 , 4 , 5 ) # Setting length of the vector length(x) < - 2 length(y) < - 7 length(z) < - 3 # Getting elements of the # new vectors x y z |
Output:
[1] 3 NA [1] 1 2 3 4 5 NA NA [1] 1 2 3
