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.
