ggplot2: Changing the order of stacks on a bar graph

Question

I\'m trying to make a stacked bar graph with a facet_wrap, but I want the order of my stacked variables (\"developed\") to be flipped. I\'ve reordered the factors, and trie

Answer 1

Fwiw, here is a solution with dplyr, and it uses scale_fill_manual to be explicit about the colors:

library(ggplot2)
library(dplyr)

developed=rep(c("developed","available"),6)
agriculture=rep(c(rep("loi",2), rep("dryland",2), rep("agroforestry",2)),2)  
acres=c(7435,24254,10609,120500,10651,75606,6037,9910,4390,895,9747,46893)
islands=c(rep("All islands",6), rep("Oahu",6))
all_is2=data.frame(developed, agriculture, acres, islands)

all_is2$agriculture=factor(all_is2$agriculture,levels=c("loi","dryland","agroforestry"))
#all_is2$developed=factor(all_is2$developed,levels=c("available","developed"))

all_is3 <- all_is2 %>% group_by(islands,agriculture,developed) %>% 
                       summarize(acres=sum(acres)) 

ggplot(all_is3,aes(x=agriculture,y=acres,fill=developed))+
  geom_bar(position="stack", stat="identity")+
  facet_wrap(~islands)+ 
  xlab("")+ylab("Acres")+theme_bw() +
  scale_fill_manual(name="",values=c("available"="black","developed"="light gray"))
