Hello,
I'd like to add labels to my plot that include a male or female symbol as
subscript.
I'm working in Windows Vista and R 3.0.0.
I am able to add the male symbol to the plot as regular text (NOT as
subscript), e.g. with:
mtext("Male\u2642")
This displays the word "Male" followed by the male symbol on the plot.
But "\u2642" does not work when I try to put it as a subscript.
For example,
mtext(expression("Male"["\u2217"]))
successfully adds an asterisk as a subscript after the word "Male".
However,
mtext(expression("Male"["\u2642"]))
displays the word "Male" followed by a subscript of "<U+2642>", i.e. the
symbol is not displayed.
How can I make the male symbol show as a subscript?
You cannot use non-native text with plotmath. The issue is not that you
used a subscript but that you passed an expression() call and hence
invoked plotmath. And the help does say
In non-UTF-8 locales there is normally no support for symbols not
in the languages for which the current encoding was intended.
Many thanks for any suggestions!
Read all of ?plotmath.
Cheers,
Emily
