[R] Spacing of text does not match spacing of bars in barplot

[William Dunlap]

The return value of barplot contains the locations
of the bars that it just drew.  Use that instead of
1:8 when you draw the text:

 > barCenters <- barplot(X2sum)
 > text(barCenters, par("usr")[3] - 0.5, srt = 45, adj = 1, labels =X2.labels, xpd = TRUE)

Look at help(barplot) for details.
