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?
?strsplit
