Hi
I would like to know how to pivot a table that will sum the number of plants
(a or b) for each location (x,y,z)
I have read on the listserve similar questions but which involve summing up
numbers rather than factors. I have also read about the R package reshape
on the listserve but wanted to know if there's a way to do it easily without
the package
Thanks for the help!
location plant
x a
x b
x b
y b
y b
y a
z a
z a
into a table like this
x y z
a 1 1 2
b 2 2 0
