The natural way for statisticians is to use a boxplot, and ggplot2 makes that easy: qplot(class, hwy, fill=factor(year), data=mpg, geom="boxplot", position="dodge")+theme_bw() But Jarrett Byrnes, a marine community biologist, wanted to use I get this error now :/ > df1 <- transform(df, mean=rowMeans(df[cols]), sd=apply(df[cols],1, sd)) Error in [.data.frame(df, cols) : object 'cols' not found –tlorin Apr 21 '15 at 11:54 sorry Why are there so many different amounts received when receiving a payment? r ggplot2 bar-chart share|improve this question **asked Apr 21 '15** at 9:32 tlorin 173213 1 beware by doing t(plot) you completely inversed the gene ;) –Colonel Beauvel Apr 21 '15
