Hey Folks, Do any of you remember how to sort a dataframe based on single numerical variable? I know this question came up earlier in the semester but I don't remember the answer any more........ Thanks, Nirmala

Check out order(). You want something like: x[order(x$var),] where x is your dataframe. Dave Nirmala Ravishankar writes:

New subject: Plotting

Thanks, Dave. A quick question about plot() and xyplot(). How does one move the x or the y axis? I am trying to plot ratios ranging from 0.77 to 1.3 in a bargraph, with the y axis at x = 1. I want ratios greater than 1 to appear as on the right side of the y-axis and the ratios less than 1 to appear on the left. My dataframe US looks like this State Ratio MA 1.3 CT 1.02 TX 0.9 AK 0.77 When I do barchart(formula = State ~ Ratio, data = US), the y axis is positioned at x = 0.7. How do I move it to x = 1?

Not sure. Judging by the exams, at least 1/2 the class knows more about lattice than I do. ;-) This would be a fine question for R-help, although you should, in that case, provide the code that creates the dataframe so that people can play with your data directly. Dave Nirmala Ravishankar writes:
