How to print a factor vector without levels in R?

R ProgrammingServer Side ProgrammingProgramming

To print a factor vector without levels in R, we can follow the below steps −

  • First of all, create a factor vector.
  • Then, use as.character function to read the vector.

Example 1

Create a factor vector

Let’s create a vector called f1 as shown below −

 Live Demo

f1<-factor(sample(LETTERS[1:3],20,replace=TRUE))
f1

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

[1] A B B A C C C B C B B A A B B C B A A C
Levels: A B C

Print the factor vector without levels

Using as.character function to print factor vector f1 without levels −

 Live Demo

f1<-factor(sample(LETTERS[1:3],20,replace=TRUE))
as.character(f1)

Output

[1] "A" "B" "B" "A" "C" "C" "C" "B" "C" "B" "B" "A" "A" "B" "B" "C" "B" "A" "A"
[20] "C"

Example 2

Create a factor vector

Let’s create a vector called f2 as shown below −

 Live Demo

f2<-factor(sample(c("Male","Female"),120,replace=TRUE))
f2
[1] Male Male Female Female Female Female Male Female Female Male
[11] Male Female Female Female Female Male Female Female Female Female
[21] Male Male Male Female Female Female Female Male Male Female
[31] Female Male Male Male Male Male Male Male Male Female
[41] Female Male Male Female Male Male Male Female Female Male
[51] Female Male Female Male Female Male Female Female Male Female
[61] Male Male Female Female Male Female Female Male Female Male
[71] Male Male Female Female Female Male Female Female Female Male
[81] Female Male Male Male Male Female Male Male Female Male
[91] Male Male Female Male Female Male Male Female Male Female
[101] Male Female Female Female Male Male Male Male Male Female
[111] Male Female Male Female Female Male Female Female Male Male
Levels: Female Male

Print the factor vector without levels

Using as.character function to print factor vector f2 without levels −

 Live Demo

f2<-factor(sample(c("Male","Female"),120,replace=TRUE))
as.character(f2)

[81] "Female" "Male" "Male" "Male" "Male" "Female" "Male" "Male"
[89] "Female" "Male" "Male" "Male" "Female" "Male" "Female" "Male"
[97] "Male" "Female" "Male" "Female" "Male" "Female" "Female" "Female"
[105] "Male" "Male" "Male" "Male" "Male" "Female" "Male" "Female"
[113] "Male" "Female" "Female" "Male" "Female" "Female" "Male" "Male"

Example 3

Create a factor vector

Let’s create a vector called f3 as shown below −

 Live Demo

f3<-factor(sample(c("Low","Medium","High"),120,replace=TRUE))
f3
[1] Medium High Medium High Medium High Low Low High Medium
[11] High Low High Medium Medium Low Medium Low High High
[21] Medium Medium Low Low High Low High Medium High Medium
[31] Low Low High High Low Low High Low Low High
[41] High Low High High Low High High Medium High Medium
