Creating a dataframe from a vector of character strings
You could use ?unlist:
structure(data.frame(
matrix(unlist(strsplit(beatles," ")),length(beatles),2,T)),
names=c("FirstName","LastName"))
Note that this compact code does not guard you against typos, that is
names with >2 or <2 elements.
Hope that helps,

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. -- View this message in context: http://r.789695.n4.nabble.com/Creating-a-dataframe-from-a-vector-of-character-strings-tp3450716p3450716.html Sent from the R help mailing list archive at Nabble.com.
