How to only make one legend name italic in base R plot?
I want to add a legend to a plot in which only one of the legend names is italicized. I'm using
plot() in base R.
- However, I need that italicized line to contain variable numbers, so I use
What I've tried does not work:
a <- 2 ; b <- 5 plot(a,b) l1 <- bquote(Italic ~ .(a) + .(b)) l2 <- bquote(a + b) legend(x='topright',legend = bquote(italic(.(l1)))) legend(x='topleft',legend = c(bquote(italic(.(l1))),l2))
- Notice that when I leave the expression on its own (RIGHT LEGEND), it italicizes correctly. However, when I add the text for other legend lines, it messes up (LEFT LEGEND).
How do I properly do this?
Note: I'd rather have a solution that doesn't require multiple calls to
You could use
text.font = 3, say:
legend(x='topleft',legend = c(bquote((.(l1))),l2), text.font=c(3,1))
