Partial Italic and Bold text in R

Question

I want to label a subgroup in R-plot as Non-Enterobacteriaceae

text(-1.5, c(21), pos = 4, c("Non-Enterobacteriaceae"), font = 2, cex = 0.8)

Changing the font = 4 changes the complete word Non-Enterobacteriaceae to Non-Enterobacteriaceae Any suggestions?

Answer 1

You can use some of the ?plotmath formatting options. For example

plot(c(1,10), c(1,10))
text(5, 5, pos = 4, quote(bold("Non-") * bolditalic("Enterobacteriaceae")), cex = 3)
