with_motif <- 100 without_motif <- 400 dt <- data.frame(with_motif,without_motif) The following code will plot a bar-chart using ggplot2 library, bar_plot <- ggplot(melt(dt),aes(variable,value)) + geom_bar() + scale_x_discrete(name="with or without") + theme_bw() + It describes the effect of Vitamin C on tooth growth in Guinea pigs. Choose your flavor: e-mail, twitter, RSS, or facebook... ggplot offers geom_errorbar() but I would be glad to know different ways for deriving the standard errors(deviation) so as to calculate the errorbar limits(CI).

Here we start by specifying the dodge (the spacing between bars) as well as the upper and lower limits of the x and y axes. Etymology of word "тройбан"?
