Plot of multiple data sets

Hello ! There is something quite simple I want to do with R but I found nowhere in the help how to do it. I just want to plot data which are in a matrix, every column being a data set and having the same x-axis (just an index). So for example if I have a 50 x 6 matrix I want 6 set of points on the same plot. I tried plot,new() plot(MATRIX[,1]) plot(MATRIX[,2]) ... but it replaces the previous plot each time.
Others have already mentioned matplot, lines and points but just to add to the list, if your problem is a time series then you could also use plot.zoo: library(zoo) z <- zoo(MATRIX, x) plot(z, plot.type ="single") # one plot plot(z) # separate plots
