Compute a Sequence of Equally Spaced Round values in R Programming – pretty() Function

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:

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

Output:

[1]  0 10 20 30 40 50

Example 2:

# 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:

# Create example vectors
x <- 1:50
y <- 1:50

# Create plot of two vectors
plot(x, y,

     # Default axis labels
     main = " Axis Labels")

Output:
