pretty() function in R Language is used to decide sequence of equally spaced round values.

Syntax: pretty(x, n) Parameters: x: It is defined as vector data n: length of resultant vector Returns: data vector of equal length interval

Example 1: 

r




# Create example vector
# Apply pretty function to vector
x <- 1:50                                
pretty(x)                                    


Output:

[1]  0 10 20 30 40 50

Example 2: 

r




# Create example vector
x <- 1:50    
 
# Apply pretty function to vector                           
pretty(x, n = 10)                  


Output:

 
[1]  0  5 10 15 20 25 30 35 40 45 50

Here n = 10 states that the interval vector consisting of ten intervals, i.e. n+1 elements. Example 3: 

r




# Create example vectors
x <- 1:50
y <- 1:50  
 
# Create plot of two vectors                      
plot(x, y,       
    
     # Default axis labels                    
     main = " Axis Labels")            


Output:

Example :

R




# Generate some data
x <- seq(0, 10, length.out = 100)
y <- sin(x)
 
# Create a plot of the data
plot(x, y, type = "l", col = "blue", lwd = 2, main = "Sine Function",
     xlab = "x", ylab = "y")
 
# Add tick marks to the x-axis
ticks <- pretty(x, n = 10)
axis(1, at = ticks, labels = round(ticks, 2))


output :
