Hi I am trying to plot two data set in the same picture window without overlapping with each other. I am using the format plot(x1,y1,x2,y2) but get the following error message: >plot(as.numeric(r0[,4]),as.numeric(r0[,7]),as.numeric(r0[,4]),as.numeric(r0[,7][ind[,1]])) Error in plot.window(xlim, ylim, log, asp, ...) : invalid 'ylim' value Can anyone tell me what went wrong?

Good morning, i'm drawing a barplot (data are stored in a matrix,nrow=3,ncol=10). So i get 10 groups each containing 3 sub-bars. I need to change the range of the y-axis when i plot respectively the first and the other two sub-bars in each group. I can't manage. Could you help me? Thank you. Angela

Usually the y-axis is shown on the left-hand-side of a graph, is it possible to artifically creat one more y-axis on the right-hand-side in R? What is the main reference? Thank you in advance. [[alternative HTML version deleted]]
