The correct answer is A. split.
The split function is used to split a character vector into a vector of character vectors by splitting on a specified character or regular expression. The strsplit function is used to split a character vector into a vector of character vectors by splitting on a specified character or regular expression, but it also allows for more complex splitting patterns. The autsplit function is not a built-in function in R.
Here is an example of how to use the split function to split a name into first and last name:
“`
names <- c(“John Doe”, “Jane Doe”, “John Smith”)
split(names, names)
[[1]]
[1] “John” “Doe”
[[2]]
[1] “Jane” “Doe”
[[3]]
[1] “John” “Smith”
“`
Here is an example of how to use the strsplit function to split a name into first and last name:
“`
names <- c(“John Doe”, “Jane Doe”, “John Smith”)
strsplit(names, “\s+”)
[[1]]
[1] “John” “Doe”
[[2]]
[1] “Jane” “Doe”
[[3]]
[1] “John” “Smith”
“`
