compare different datasets with stacked bar graphs in R

Question

I need to compare two different methods that each of them has 3 different results in one graph with using stacked bar style.

I want to draw a plot so that x axis shows t

Answer 1

You said that you need to compare the methods. If you represent experiment on x-axis and result on y then how will you represent method??? My way of doing it is using the facet. Here is the code for how to do it using ggplot2.

dat <- read.csv("data.csv")
library(reshape2)
library(ggplot2)
dat1 <- melt(dat,id.vars = c("experiment","method"))
p <- ggplot(dat1,aes(experiment,value,fill=variable))+geom_bar(stat="identity")+
      facet_wrap(~method,nrow=1)
p
