R : Integer Data type

You can create an integer variable, by suffixing value with ‘L’.

> class(num1)

[1] "numeric"

> num1<-10L

> class(num1)

[1] "integer"

You can convert a real value to integer, by using as.integer().

> num2 <- as.integer(2.34)

> num2

[1] 2

You can convert string to integer in same way.
