any function in R similar to the "scan" function in SAS?
You can read from a character vector as if it were a file like this:
x <- c("1-2", "3-4", "5-6")
read.table(textConnection(x), sep = "-", col.names = c("one", "two"))
one two 1 1 2 2 3 4 3 5 6

I am wondering if there is any function in R that is similar to the "scan" function in SAS. I have a data.frame which has two columns as the following: one ? two 1 ? ? ?2 3 ? ? ?4 5 ? ? ?6 I used the "paste" function to create the third column: three <- paste(one,'-',two,sep="") so the data.frame is like this now: one ? two ? three 1 ? ? ?2 ? ? ? 1-2 3 ? ? ?4 ? ? ? 3-4 5 ? ? ?6 ? ? ? 5-6 My question is, is there any function in R that can do the opposite thing to what "paste" does? suppose I only have the third column "three" now, and I want to get the first and second columns. If in SAS, I can do the following: one = scan(three,1,'-') two = scan(three,-1,'-') How can I do this in R? thank you, karena -- View this message in context: http://r.789695.n4.nabble.com/any-function-in-R-similar-to-the-scan-function-in-SAS-tp2131264p2131264.html Sent from the R help mailing list archive at Nabble.com.
