- I run these simple code in R and I don't know why it doesn't return the correct order.
order(c(4,1,4,3,2))
order(c("R","C","R","I","J"))
- This is the results:
[1] 2 5 4 1 3
[1] 2 4 5 1 3
- What is the problem?

The function order() returns the id (location) of the sorted elements. You could use:
v1 <- c(4,1,4,3,2)
v2 <- c("R","C","R","I","J")
sort(v1)
sort(v2)
#or
v1 <- v1[order(v1)]
v2 <- v2[order(v2)]
