Visual representation

Example 1: Converting a float to an integer

r_float <- 11.21
print(r_float)
print(typeof(r_float))

r_int <- as.integer(r_float)
print(r_int)
print(typeof(r_int))

Output

[1] 11.21
[1] "double"
[1] 11
[1] "integer"

Example 2: Check if a variable is an integer

Use the is.integer() function to check if a variable is an integer.

r_float <- 11.21
r_int <- as.integer(r_float)

print(is.integer(r_int))

Output

[1] TRUE

That’s it.
