Title
Body
I am trying to plot this data in R: column1 column2 column3 1-2 abc 10 1-2 def 15 1-2 ghi 20 2-3 abc 80 2-3 def 95 2-3 ghi 10 3-4 abc 30 3-4 def 55 3-4 ghi 80 The x axis would be column1 (so 1-2, 2-3 and 3-4 would be present as the x axis), and on y axis, the values in column3 should be plotted for each of the column2 elements. So this would be a "grouped" bar chart essentially. I am not able to plot this grouped bar chart using R. The code snippet I am using is below: dataset <- fetch(rs,n=-1) plot_var <- table(dataset$percentage, dataset$age) barplot(plot_var, names.arg, main="Title of Graph", xlab="Column1", col=c("darkblue","red"), legend = rownames(plot_var), beside=TRUE) How do I get this grouped bar chart to display?
