R help - May 2011 - Simple ordering or sorting question

Greetings,

I'm trying to simply reorder a data frame on the row numbers.  So, for 
example, instead of getting 1,2,3,4,5,6,7,8,9,10,11, ... 100 ...,  I get 
instead
1, 10, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 11, ...   I've 
tried commands such as

df <- df[order(rownames(df)),] and

and have substituted the order command with sort and sort.list to no 
avail.  Any advice would be appreciated.  Thanks in advance.

David

It looks like your row numbers are "characters" because that is the
sort sequence you are getting. Try

df <- df[order(as.numeric(rownames(df))), ]
