Hi All,

I am looking for help in rotating species titles produced using the
strat.plot( ) function in the rioja package.  This function produces a
stratigraphic plot of paleoenvironmental data.  Currently the titles of each
species are plotted vertically while they are typically plotted at a 45
degree angle in other programs.  Does anyone have any idea of how to rotates
these titles?

Below is an example plot (taken from the rioja help file) made the
function.

Cheers,
Brendan Wiltse

library(vegan) ## decorana
data(RLGH)

library(rioja)
## Not run:
# create appropriately sized graphics window
windows(width=12, height=7) # quartz() on Mac, X11 on linux
## End(Not run)
# remove less abundant taxa
mx <- apply(RLGH$spec, 2, max)
spec <- RLGH$spec[, mx > 3]
depth <- RLGH$depth$Depth
#basic stratigraphic plot
strat.plot(spec, y.rev=TRUE)
#scale for percentage data
strat.plot(spec, y.rev=TRUE, scale.percent=TRUE)
# plot by sample depth
strat.plot(spec, yvar = depth, y.rev=TRUE, scale.percent=TRUE,
title="Round Loch of Glenhead", ylabel="Depth (cm)")
