问题
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?
回答1:
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.
回答2:
In the y-axis or label?
plot(1,1, ylab = expression(X >= 5))
Try ?expression
and ?plotmath
.
