I have a data frame:
head(cat1)
expl.val pred.val
1 0.602
1 0.602
1 0.602
1 0.602
1 0.604
1 0.604
I want to calculate the mean of the pred.val for the different expl.val, which are values from 1 to 14. And put it in a new data frame.
Something like this:
expl.val pred.val
1 mean of expl.val(1)
2 mean of expl.val(2)
3 mean of expl.val(3)
4 mean of expl.val(4)
5 mean of expl.val(5)
6 mean of expl.val(6)
How can I do this?
