Hello.

I am trying to get my axis label to read as follows

(The symbol) Delta AUC blah blah...
then below it...(some other text)

The problem is the Delta symbol shows up beside the "(some other text)" rather than the "AUC". Does any one know how I can get the Delta to remain beside AUC?

Here is the actual command should you care to look at it.

par(mar=c(8,8,4,4))
par(adj=.5)
par(font.lab=2)

barplot(c(5724.688,7290.7875), ylab=expression(paste(Delta,"AUC 45-200 min
\n(μg/ml * 155 min)"), xlim=c(0,1), width=0.16,
border="black",font.lab=2,cex.lab=2.1,cex.names=2, names.arg=c("Saline
\n(n=8)", "Exendin\n(9-39) (n=8)"),mgp=c(3,4,0), axisnames=TRUE,
ylim=c(0,10000), col=c('grey88','grey71'), axes=FALSE, lwd=2, space=.5)

axis(2, at=c("0", "2000", "6000","10000"), lwd=2, font=1.7, pos=-.025,cex.axis=2)

abline(h=0, untf=FALSE, lty=1, lwd=2)

arrows(.4, 8297.291, .4, 6284.284, code=3, angle=90, lwd=2) arrows(.16,7071.79,.16,4377.585, code=3, angle=90, lwd=2)

Thanks all!
