hello, I would like to create the following barplot:
I have 4 different data sets (same length + stddev for each data point) data1 sd1 data2 sd2 data3 sd3 data4 sd4 now, I'd like to plot in the following way: data1[1],data2[1],data3[1],data4[1] with it's sd-values side-by-side at one x-axis label (named "position 1") and each bar in different colors. data1[2],data2[2],data3[2],data4[2] at the next x-axis label (named "position 2") with the same color scheme and so on over the whole length. I managed to plot one set in the following way: par(mai=c(1.5,1,1,0.6)) plotInfo <- barplot(data1, las=2, ylim = c(0,plotMax+1), ylab = "Percentage") arrows(plotInfo,data1,plotInfo, data1 + sd1, length=0.1, angle=90) arrows(plotInfo,data1,plotInfo, data1 - sd1, length=0.1, angle=90) could anybody give me a help on this?
