Dear R experts---is it possible to plot the \ell symbol in R under the
pdf device? the following did not work:
pdf(file="ell.pdf");
plot( c(0,1), c(0,1) );
text( 0.5, 0.5, "\u2113" )
dev.off()
my guess is that this cannot be done, but I thought I would ask.
(On a Mac:)
After 7 warning messages I got an ellipsis ("...") printed at the
desired location. Interestingly I think the error message might have
properly printed the desired glyph (assuming you wanted a cursive
lower case "l":
Warning messages:
1: In text.default(0.5, 0.5, "ℓ") :
conversion failure on 'ℓ' in 'mbcsToSbcs': dot substituted for <e2>
I also looked in the Hershey fonts without recognition (but could have
missed one). One the Mac there is an option among the Zapfino family
but I suspect that is of little use to you.
