Ok. I just figured out what the problem was.
I had to attach() the data.
**
x1=data1[,,2]
tx1=t(x1)
*ttx1 *= cbind(tx1 , obs=1:nrow(tx1))
--> this is how ttx1 was made; and of course, in ttx1, there is a variable
called 'obs'.
I had to attach(ttx1) first before I use this: *sortedx1=ttx1[order(-obs),]*
But it seems that, I cannot attach ttx1.
*> attach(ttx1)
Error in attach(ttx1) :
'attach' only works for lists, data frames and environments*
Of course, this is one of the ways I can do. But I just don't think I can do
it for 1916 times.
> write.csv(ttx1,"c:/i.csv")
> m=read.table("c:/i.csv", header=T, sep=",")
> attach(m)
> sortedx1=m[order(-obs),]
Do you know what I should do?
Thanks.
