How to include italics in the main heading to my graph?

Question

Here is the code I have atm;

plot(V1,V2,pch = 19, main = \"Changes in absolute cell volume of Chlorella Alga over a 24hr period\", xlab = \"Stage in 24hr cycle\"         


        

Answer 1

use italic( )

mn <- expression(paste("Changes in absolute cell volume of", italic(" Chlorella "), "Alga over a 24hr period"))

plot(V1,V2,pch = 19, 
     main = mn, 
     xlab = "Stage in 24hr cycle",  
     ylab = "Absolute cell volume(µm^3)",
     xlim = c(0,24), ylim = c(32.5,188))
