R help - Apr 2009 - text in graph with expression

Hi all,
 
I'm using 'expression' in the axes labels in graphs to get the greek
letters
(ylab), as follows:
 
plot(
 layer_1$U0
 ,layer_1$dP/(H1.Theo)
 #,ylim=c(0,100)
 ,xlim=c(0,1.1)
 #,main="Pressure Drop",
 ,xlab=expression(U[0]~(Nm/s))
 ,ylab=expression(Delta~P~(Pa/m))
 ,col=2
 ,pch=16
 ,cex=1.5)
 
I just need to know how to avoid the use of a space (~) between the greek
letter (Delta) and the rest of the text.
 

Regards/Cordialement

Use "*", see ?plotmath
