[R] Rotating Titles

[Uwe Ligges]

Edit the strat.plot function, particularly the line

         text(tks1[1], pos, labels = colnames(d)[i], adj = c(0,
             1), srt = 90, cex = cex.xlabel, xpd = NA)

where the rotation is hardcoded  or ask the maintainer to make it an 
argument to the function so that you can change it on calling the plot 
function.
