Adjust axis limit in bar plot ggplot2

Question

Can anyone help me to set the limits of the horizontal axis in the figure to (0,1) please? The code below does not work.

set.seed(234)
data <- data.frame(var1 = c(rep('A',3),rep('B',3)),
                   var2 = runif(6), 
                   var3 = rep(c('x1','x2','x3'),2))

ggplot(data,aes(x=var1,y=var2,fill=factor(var3))) + 
   geom_bar(stat="identity",position="dodge") + 
   scale_y_continuous(breaks=c(0,0.5,1.0)) +
   coord_cartesian(ylim=c(0,1.0)) +
   coord_flip()

No need for coord_cartesian(), you can pass the ylim arg into coord_flip() directly.

set.seed(234)
library(ggplot2)
data <- data.frame(var1 = c(rep('A',3),rep('B',3)),
               var2 = runif(6), 
               var3 = rep(c('x1','x2','x3'),2))

ggplot(data,aes(x=var1,y=var2,fill=factor(var3))) + 
  geom_bar(stat="identity",position="dodge") + 
  scale_y_continuous(breaks=c(0,0.5,1.0)) +
  coord_flip(ylim = c(0, 1))
