Hi Pedro, If I get the idea, you want a vector of length 7300 starting at 1 and ending at 0.
seq(1,0,length.out=7300) Produces such a vector. It seems to me that: seq(1.1,0.05,length.out=7300) produces the upper vector and: seq(0.95,-0.05 length.out=7300) the lower. Then again, I might have the wrong idea big time.
