do 'str' on your object to see if you have factors where you think you

Hi everybody, this is a real dummy thing.
I sorted a matrix based on a given column, and what I get is right,
until it comes to columns of negative and positive values; than,
"order" orders everything from max to min in the negative values,
and then AGAIN from max to min in the positive values!!!
Why isn't everything order from max to min, and that's it?
Thank you!!!
Attached is the txt file I use; try:
x=x[order(x[,2]),]
What I get is:
print(x)
