Hi all
I have a bit of a problem.  I want to make a barplot of some data.  My
data is of a score that is separated by year and by a limit (above 3 and
below 3 to calculate the score).
Year	Limit	HSS
1999	ALT	0.675
1999	VFR	0.521	
2000	ALT	0.264
2000	VFR	0.295

I would like to have a barplot with year on the x axis and HSS on the y
axis and the two limits as two different colors to show the difference.
Using (dataset$HSS, col=c("green","purple"))  I  get some of the plot
but I don't know how to get labels on the bottom for each year and I
can't get a legend for my barplot.  Not really sure what I am doing
wrong but any help would be much appreciated.
