R help - Jul 2012 - order or sort doesn´t work properly

Hi all,

I want to order a series that is included on the second column in MCT.csv.

I do but R doesn?t order, could be because is a csv?

I have prove

MCT<-read.csv("MCT.csv")

a<-order(MCTor[,2],2,decreasing = FALSE)


a<-order(MCTor[,2],1,decreasing = FALSE)

or the same with sort but didn?t worked.

It is suposed that a will have the ordered on ascending or descending
direction, doesn?it?

1. That you think order() or sort() "did not work " is preposterous.

2. I suggest that you carefully read both ?sort and ?order, as you
obviously do not understand what these functions do. Here is a hint to get
you started:
> 3:1
[1] 3 2 1
> order(3:1)
[1] 3 2 1
> sort(3:1)
[1] 1 2 3

# MCT ordered by the second column of MCT, from smallest to largest values
MCT[order(MCT[, 2]), ]
