If you have your data organized in a matrix like the one printed at the
bottom of your jpg, barplot will produce the same graph:
> set.seed(42)
> a <- matrix(round(runif(45)*100, 0), nrow=5, ncol=9)
> a
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9]
[1,] 91 52 46 94 90 51 74 83 38
[2,] 94 74 72 98 14 39 81 1 44
[3,] 29 13 93 12 99 91 39 21 4
[4,] 83 66 26 47 95 45 69 91 97
[5,] 64 71 46 56 8 84 0 61 43
> barplot(a)
> barplot(a, beside=TRUE)

"VADeaths" is plotted over time? I'm hoping to have multiple variables
plotted over time, with the bars clustered by variable so that you can
see
how each variable changes over time.
