Thanks Bert and Peter, Yes Bert, I was aware of the legend() function syntax, and just quoting the legend argument within the function.
However, Bert and Peter, I do not understand why it works with your absolutely reproducible examples and not in the slightly (not so slightly apparently) different context where I used it... densren=1.25 plot(1:100,1:100,type="n") legend(list(x=0,y=100),legend=c("Sans renard",bquote(.(densren) (ind./km)^2)),lty=c(1,2),col=c("black","red"),bty="n") densren=1.25 plot(1:100,1:100,type="n") legend(list(x=0,y=100),legend=c("Sans renard",bquote(.(densren) * " ind."/"km"^2)),lty=c(1,2),col=c("black","red"),bty="n" Probably because the result of bquote() is concatenated in a character vector, but how to deal with this ?
