[R] rotating axis labels in plot with multiple plots

I have a plot like this, consisting of 18 different vioplots:

(monospaced font)

This I create in such a way that in the graph itself plot 1 appears in the top left corner, and plot 18 in the bottom right corner. I then flip it around when I show it in my paper (it was simpler to do it that way, this might change:)).

I am now trying to make labels a to f, which are a set of numbers which are _local_ to each graph group. Now I would like these numbers to be either vertical to the axis (so that they are in normal text direction when the paper is rotated so that graphs 18-16 are on top), or possibly 45 degrees to the plot group.

This is the way I create labels and such:

        plot.window(xlim = xlim, ylim = ylim)
        axis(2, at = at, labels=toptitle, tick=FALSE)
        if(!bottom) {
          if(!left){ # nothing > ok
            axis(1, at = at, labels = label, tick=FALSE)

else{ # not bottom, but left axis(1, at = at, labels = label, las=2)
} else{ text(lognumbers, par("usr")[3] - 0.25, srt = 135, adj = 1,labels = loglabels, xpd = TRUE) if(!left){ # bottom, but not left # want to replace this one with the text # axis(4, at = lognumbers, labels=loglabels, las=2)
else{ # bottom and left > not ok axis(1, at = at, labels = label, las=2) # want to replace this one with the text # axis(4, at = lognumbers, labels=loglabels, las=2)
} }

In this sceme graphs 18-16 are defined as being left, whereas graphs 3, 6, 9, 12, 15, 18 are defined as bottom.

My question relates to my attemt to set nice-looking axis labels using text. When I put them on as they are shown here, they show up on (relative to image above) the left side of the "bottom" graphs. How do I get them to show up on the side I would like them to?

Hope this was somewhat understandable...:)
