I have a vector of character strings that I would like to split in two, and
place in columns of a dataframe.
So for example, I start with this:
beatles <- c("John Lennon", "Paul McCartney", "George Harrison", "Ringo
Starr")
and I want to end up with a data frame that looks like this:
> Beatles = data.frame(firstName=c("John", "Paul", "George", "Ringo"),
lastName=c("Lennon", "McCartney", "Harrison",
"Starr"))
> Beatles
firstName lastName
1 John Lennon
2 Paul McCartney
3 George Harrison
4 Ringo Starr
I tried string-splitting the first vector on the spaces between first and
last names, and it returned a list:
> strsplit(beatles, " ")
[[1]]
[1] "John" "Lennon"
[[2]]
[1] "Paul" "McCartney"
[[3]]
[1] "George" "Harrison"
[[4]]
[1] "Ringo" "Starr"
Is there a fast way to convert this list into a data frame? Right now all I
can think of is using a for loop, which I would like to avoid, since the
real application I am working on involves a much larger dataset.
