Question

X <- 0:6, then as.numeric(x) or as.logical(x), as.complex, or as.character(x) converts all objects in the vector to _____.

A) Numeric.
B) Logical.
C) Complex.
D) Character.

Answer 1

In R, the vector x defined as 0:6 can be converted to numeric, logical, complex, or character types using the as.numeric(x), as.logical(x), as.complex(x), or as.character(x) functions respectively. The correct conversions for each function are A) Numeric, B) Logical, C) Complex, and D) Character. The function used determines the type to which x will be converted.

Step-by-step explanation:

If x is defined as 0:6 in R, then this means that x is a sequence of numbers from 0 to 6. In R, you can convert this sequence to different types using various conversion functions:

• as.numeric(x) will convert x to numeric class.
• as.logical(x) will convert x to logical class; in R, 0 is considered FALSE and any number other than 0 is considered TRUE.
• as.complex(x) will convert x to complex class, i.e., a complex number with the original numbers as the real part and 0 as the imaginary part.
• as.character(x) will convert x to character class, effectively making the numbers into text.

Now, each of these functions will convert x to the type implied by their names. Hence, the correct options for what they convert x to are:

1. Numeric
2. Logical
3. Complex
4. Character

Therefore, it depends on the function used what x is converted to. So, please mentioned correct option in final answer:

1. A) Numeric.
2. B) Logical.
3. C) Complex.
4. D) Character.
