Hi,
I need to calculate the average length of a trait per individual. I am not
used to working with R so I could use some help.
The table goes like this:
ind trait
1 3.6
1 3.8
1 3.9
1 3.6
2 5.5
2 5.2
3 4.8
3 4.5
and so on...
If I type mean(trait) it will give me the average of all the individuals and
I need a list of averages per individual.
Can you help me please?
