Sequence from 2 Vectors
enum.list <- function(x,y) {
mylist <- NULL
for(i in 1:length(x)) {
mylist[[i]] <- x[i]:y[i]
}
xx <- unlist(mylist)
}
a <- c(1,2,3)
b <- a+2
(harry <- enum.list(a,b) )

a<-c(1,2,3) b<-a+2 b
[1] 3 4 5 I would like to have a vector that is a sequence which starting from a and ending at b c = c(1:3,2:4,3:5) c = c(1,2,3,2,3,4,3,4,5) Thank you Best Regards, Suphajak Ngamlak Equity and Derivatives Trading Phatra Securities Public Company Limited Tel: +662-305-9179???
