Hello, I have a problem about using the command "plot". Suppose I have some points, and one of them is (0,0), how can I show the figure with this point which is at the corner?
How close to the corner do you want it? > plot(0, 0, xlim=c(0, 1), ylim=c(0,1)) you could also add: > grid()

By default, R adds +/- 4% to each axis range, based upon the range of the x and y values or the 'xlim' and 'ylim' arguments. This behavior is set by pars 'xaxs' and 'yaxs', which are set to "r" by default. Setting both to "i" will provide exact axis ranges. Note the difference between: plot(0:5, 0:5) and plot(0:5, 0:5, xaxs = "i", yaxs = "i") See ?par for more information. HTH, Marc Schwartz
