Hi,
I wonder if this is something on my machine locally or R in general.
When I do the following:
plot(c(0,1),c(0,1),main=expression(paste(symbol("D"),"D",sep="")))
I get a plot with a title having uppercase delta followed by "D".
But in
the following
pdf(file="deltaTest.pdf")
plot(c(0,1),c(0,1),main=expression(paste(symbol("D"),"D",sep="")))
dev.off()
The more predictable way to get "GreekDelta"-D would be:
> pdf(file="deltaTest.pdf")
> plot(c(0,1),c(0,1),main=expression(Delta*D))
> dev.off()
I.e., using the symbol font cap-delta the way is is supposed to be
used, and not misusing the paste() platmath function, which is both
unnecessary here and misleading as to standard plotmath syntax.
the uppercase delta looks like O with overstrike slash, i.e. Ø.
Other greek alphabets, such as Gamma, seem to work fine for pdf as
well.
My sessioninfo for this is
