I have a data.frame and I need to calculate the mean per group (i.e. per Month, below).
Name Month Rate1 Rate2
Aira 1 12 23
Aira 2 18 73
Aira 3 19 45
Ben 1 53 19
Ben 2 22 87
Ben 3 19 45
Cat 1 22 87
Cat 2 67 43
Cat 3 45 32
My desired output is like below, where the values for Rate1 and Rate2 are the group means. Please disregard the value, I have made it up for the example.
Name Rate1 Rate2
Aira 23.21 12.2
Ben 45.23 43.9
Cat 33.22 32.2
