## Question

Which one of the following is NOT a Data Type?

## Options

- **A.** Numeric
- **B.** String
- **C.** Logical
- **D.** Thread

## Answer

Option D

## Explanation

Thread' is not a standard data type: Standard data types in R and most programming languages: • Numeric/Double: decimal numbers (3.14, 2.718) • Integer: whole numbers (1L, 100L in R) • Character/String: text ('hello', 'ATCG') • Logical/Boolean: TRUE/FALSE • Complex: complex numbers (3+2i) • Raw (in R): raw bytes NOT a standard data type: • Thread: a thread is a unit of CPU execution (a concurrency/operating system concept), NOT a data type. It refers to a lightweight process, not a way of storing data values. This is important in bioinformatics programming where correct data types prevent errors in analysis pipelines. Answer: 'Thread' is NOT a data type; standard types include Numeric, String/Character, Logical/Boolean, Integer, Complex.
