showing utf-8 character in chart generated by ggpl

Question

I want to use the symbol (u+2265):

in the y-axis label of my chart. How can I do that? Thanks.

UPDATE 01

I need to use add a >=95 in the y-axis label, showing the group of people aged more than 95, I tried expression(>=95) but fail as it seems to expect something before >=. What can I do?

Answer 1

In the y-axis or label?

plot(1,1, ylab = expression(X >= 5))

Try ?expression and ?plotmath.

Answer 2

qplot(1, 1, ylab=expression(phantom(.) >= 95))

By using phantom in the expression, you don't get anything printed. I put a period in there because phantom still leaves space, so I wanted something small.
