No, the spacing is not needed, just like any other spacing in R, it is ignored, but my eye-brain wetware system is /not/ the R parser and as such I like to space things out so *I* can parse and *understand* my code; I find it easier to find syntax errors etc that way. Note that there was a difference between what I posted and Baptiste's example; there the space was explicitly encoded within "temperature ", where as I use "~" as the indicator for spacing; any other spacing was just for sake of legibility. I also don't think this is non-breaking because unless you add an explicit \n (newline) in your label, the entire label will be rendered on a single line. Better to think of x ~ y (or x~y if you think that is more readable) as just putting spacing between x and y. As ?plotmath shows, you can string multiple ~ together to give extra spacing; x ~~ y And so on... Glad you got this working as you wanted.
