I am trying to get the x axis labels to be rotated 45 degrees on a barplot with no luck. This is the code I have below:

barplot(((data1[,1] - average)/average) * 100,
        srt       = 45,
        adj       = 1,
        xpd       = TRUE,
        names.arg = data1[,2],
        col       = c("#3CA0D0"),
        main      = "Best Lift Time to Vertical Drop Ratios of North American Resorts",
        ylab      = "Normalized Difference",
        yaxt      = 'n',
        cex.names = 0.65,
        cex.lab   = 0.65)
