?unique says
Value:
An object of the same type of 'x'. but if an element is equal to
one with a smaller index, it is removed.
However, I need to keep the one with the LARGEST index.
Can someone please show me the light?
I thought about reversing the row order twice, but I couldn't

Try:
largestDF - DF[nrow(DF)- which(!duplicated(rev(DF$t)))+1,]
You can then sort this however you like in the usual way. Row names will be
preserved.

I have a question about deparse function in R
What is the reason that deparse use an argument like width.cutoff ?
Why the maximum cutoff is 500?
I was manipulating an R formula and used deparse. Since the length of user's
formula was greater then 500, my code didnt work.
thanks
