You don't need to attach. But you do need to mention what kind of
object ttx1 is. I had (foolishly) assumed that it was dataframe,
but I see that it's a matrix. So try this:
ttx1[order(-ttx1[,"obs"),]

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.

It is clear that 'obs' does not exist.

It says...

Are you really sure you have 'obs'? What does 'str(obs)' show? What
about 'ls()'?

Hi guys,
I need your help.
I'm trying to sort the data by the variable "obs".
This is how I tried to sort the data below.
The problem is, I have a variable name "obs"; this is.. a counter
variable.
something like _n_ in SAS.
I do not know why it is not working.
I even tried a similar example in UCLA webpage:
http://www.ats.ucla.edu/stat/R/faq/sort.htm :it also does not seem
to
work.
"*sort1.hsb2 <- hsb2[order(read) , ]"*
Do you have any idea how to deal with this problem?? Thank you so
much.
