Question

Y <- c("a", True) will coerce the elements to all be ___.

.
A) y <- c("a", True) will coerce the elements to all be character.
B) y <- c("a", True) will coerce the elements to all be logical.
C) y <- c("a", True) will coerce the elements to all be numeric.
D) y <- c("a", True) will coerce the elements to all be character and logical.

Answer 1

In R, the expression y <- c("a", True) will coerce elements to be of type character, as character is the most flexible type when combining different data types into a vector.

Step-by-step explanation:

The question is about how R, a programming language, handles type coercion within a vector. In R, when combining elements of different types into a single vector using the c() function, all the elements are coerced to the most flexible type to ensure that all elements in the vector are of the same data type. In the given expression y <- c("a", True), there's a mix of character and logical types.

Here, 'True' is not a recognized logical value in R; the correct logical constants are TRUE or FALSE in all uppercase. However, assuming 'True' is intended to be a logical value, the correct answer would be A: y <- c("a", True) will coerce the elements to all be character. This is because character is the most flexible type among character, numeric, and logical types.
