Cut a within elements by length, not value, of vectors
Building on Erik's solution and because it would easier to do date arithmetic.. d1 <- as.character(date) d1 <- ifelse(nchar(d1)<4, paste(0,d1,sep=""),d1) d2 <- as.Date(date, "%m%d")

Hello, I have a vector, "dates", as a series of 3 digit elements, i.e. > date [1] 528 528 528 528 528 528 528 528 528 528 528 528 708 708 708 708 708 708 [19] 708 708 708 708 529 529 529 529 529 529 529 529 529 529 529 529 529 529 [37] 529 624 I need to convert them into julian, but have to insert a "/" or "-" after the first number within each element of the vector (5/28 5/28 etc). Found plenty functions to replace by a pattern but not to cut by a certain number of digits with an element. Alternately, if I could run all the elements into one long vector and then cut every one then two digits, that would work as well. Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Cut-a-within-elements-by-length-not-value-of-vectors-tp2290440p2290440.html Sent from the R help mailing list archive at Nabble.com.
