Hi fellow R users,
I have a dataset that looks something like this.
species class abundance
K 1 592
K 2 288
G 1 254
G 2 239
C 2 173
D 2 123
E 3 89
F 2 87
B 2 86
H 2 82
I 1 79
J 2 76
B 1 73
D 3 72
A 2 62
L 2 58
I want to plot a stacked barchart. species is the x-axis, abundance is
y-axis, and class will appear as the stacks in different colours. I
need the species to be displayed in descending order of abundance,
meaning species K on the left side of the graph to species L on the
right.
I've read other posts here that recommended the function reorder,
which I've used but species K appears on the right side of the graph
instead.
barchart(table$abundance ~ reorder(table$species, table$abundance),
groups = table$class, stack = T, scales = list(x = list(draw =
F)),
auto.key = list(adj = 1))
Is there anything wrong with my code?
Thanks.
Kang Min
