Here's a variation on the theme: boxplot(x[,i]) title(main = bquote(.(mainlabel1)~~italic(.(predictor[i]))~~.(mainlabel2)) )

Hello, Try this way (not sure if it's the best way, but it works): boxplot(x[,i], main=substitute(expression(paste(a," ",italic(b)," ",c)),list(a=mainlabel1,b=predictor[i],c=mainlabel2)), ylab=paste(ylabel),cex.lab=cexalabel,cex.main=cexmlabel,cex.axis=1.5) Best, Miguel On Mon, Mar 8, 2010 at 2:27 PM, Bernd Panassiti<bernd.panass...@rivm.nl>wrote:Dear R users, in the example below the name of the genus will be displayed in the main titles using the variable predictor[i] and paste.
