Set column names using colnames() function
colnames() function in R Language is used to set the names to columns of a matrix.
Syntax:
colnames(x) <- valueParameters:
x: Matrix
value: Vector of names to be set
Example: R program to set the column names using colnames() function.
R
# create two vectors with integer and string types vector1 = c(1,2,3,4,5) vector2 = c("sravan","bobby","ojsawi", "gnanesh","rohith") # display print(vector1) print(vector2) # combine two vectors using cbind() combined = cbind(vector1,vector2) # Applying colnames colnames(combined) = c("vector 1", "vector 2") # display combined |
Output:
Set Column Names when Using cbind Function in R
In this article, we are going to see how to set the column names when using cbind() function in R Programming language.
Let’s create and combine two vectors for demonstration:
R
# create two vectors with integer and string types vector1 = c(1,2,3,4,5) vector2 = c("sravan","bobby", "ojsawi","gnanesh", "rohith") # display print(vector1) print(vector2) # combine two vectors using cbind() print(cbind(vector1, vector2)) |
Output:
[1] 1 2 3 4 5
[1] "sravan" "bobby" "ojsawi" "gnanesh" "rohith"
vector1 vector2
[1,] "1" "sravan"
[2,] "2" "bobby"
[3,] "3" "ojsawi"
[4,] "4" "gnanesh"
[5,] "5" "rohith"
