The `?plotmath` help page also refers you to the help page on `?points`. I have
on several occasions used the last example on that page to create an annotated
table of glyphs associated with the Symbol font "characters" in the higher
ranges of values:
pdf(); TestChars <- function(sign = 1, font = 1, ...)
{
MB <- l10n_info()$MBCS
r <- if(font == 5) { sign <- 1; c(32:126, 160:254)
} else if(MB) 32:126 else 32:255
if (sign == -1) r <- c(32:126, 160:255)
par(pty = "s")
plot(c(-1,16), c(-1,16), type = "n", xlab = "", ylab = "",
xaxs = "i", yaxs = "i",
main = paste( "Mac Symbol: points example", sprintf("sign = %d, font =
%d", sign, font)))
grid(17, 17, lty = 1) ; mtext(paste("MBCS:", MB))
for(i in r) {
try(points(i%%16, i%/%16, pch = sign*i, font = font,...))
try(text(i%%16 -.3, i%/%16-.3, labels = i,cex=.6)) }
}
TestChars(font = 5); dev.off()

Looks to me that the 183 glyph might be to your liking. `points` has a 'cex' parameter that could be used to embolden it further if needed. -- David. > > Dennis > > Dennis Fisher MD > P < (The "P Less Than" Company) > Phone: 1-866-PLessThan (1-866-753-7784) > Fax: 1-866-PLessThan (1-866-753-7784) > www.PLessThan.com > > ______________________________________________ > [email protected] mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
