Try with(yourData, barplot(table(Type)))
or, if you really want percentages something like with(yourData, barplot(table(Type)/length(Type)*100, ylab = "Percentage")) (BTW, it would be nice to know who you are.)

I need to plot the "Type" variable as a bar plot where the x axis is the type A, B ,C or D and the y axis shows the percentage. I was not able to get a bar plot. it seems that I need to convert the categorial variable into numeric values. Is there any way how to get the bar plot without doing the conversion, Thanks -- View this message in context: http://www.nabble.com/barplot-for-a-categorial-variable-tp18743744p18743 744.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
