Insert math sign in plot title using bquote

[Cherson]

I am trying to insert a "greater than or equal to" sign in my plot title using bquote. I do get it to work but only when I type a "dot" after the "tilde". So the "dot" gets visible in the plot title, and I want to get rid of that.

This works:
main = bquote("Boxplot for MFE, h" ~. <= ~ "8")

But this doesnt work:
main = bquote("Boxplot for MFE, h" ~ <= ~ "8")

I am following the tutorial here:

Math Notation for R Plot Titles: expression and bquote | R-bloggers

How can I get it to work without the "dot"?

@Cherson

main = bquote("Boxplot for MFE, h" ~. <= ~ "8")

Lose the first ~

plot(mtcars$hp,mtcars$mpg, 
     main = bquote("Boxplot for MFE, h" <= ~ "8"))

Simple as that. Many thanks technocrat!
