Hi,
I have (x, y) data as the follows (saved in the txt file):
x y
1 8
2 5
3 3
4 +
5 -1
6 +
When I read this txt file into R and attach this data, I found the output of y
is as the follows
[1] 8 5 3 + -1 +
Levels: -1 + 3 5 8
Could I get rid of Levels in the output? Because I need to use the observed y
and x run regression first and then assign the value to the missing y later.
Thanks,
Kate
