For example, to plot the ‘e’ with acute symbol “é” you need to add the respective code \u{E9} in the label option: Here some code xdata=c(rnorm(10)) ydata=c(rnorm(10)) plot(xdata,ydata, main=”Testing […]

After many tries, I found this link saying how to solve this annoying issue. I will use my sample data I need to plot as A, PTR and MX. After you plot you need to fix the order using Factor() and Levels(). me.df$Qtype = factor( me.df$Qtype, levels=c(qname)) Now just plot again. last_plot() %+% me.df The […]
