Type Conversion
Indeed, while you can directly create integers in R by appending L to a number, converting existing values to integers requires a different approach. Simply appending L will cause an error, as demonstrated in the example below:
123# Some number num <- 20 numL # Trying using L for converting
Certainly, that did not achieve the intended result.
Luckily, R simplifies the conversion process with straightforward functions like as.double(), as.integer(), and as.complex(). The function names are quite self-explanatory!
Numerical types follow a sort of 'hierarchy' where each integer can be converted to a double or a complex number, and each double can become a complex number. However, converting a double to an integer will result in truncation, not rounding, of the number to its integer component.
Give these functions a try!

- Convert the number
9.85to aninteger. - Convert the
integer42, created withL, to adouble.
