G'day all,
I am using Cairo to produce output graphics (mainly png), but don't seem to be
able to figure out how to stop the text being rendered in italics.
I am using 10.6.2, and R version 2.10.1 Patched (2010-02-01 r51089).
Using this produces the output as I anticipated (with upright text)
png('outputs/reports_by_province2.png')
barplot(outbreaks.summary$Provinces,names.arg=outbreaks.summary$Year,
ylab='Number of provinces reporting outbreaks', cex.axis=1, cex.names=1) -> tmp
Using this produces a nicer image (the transparent background is important),
but the text is all italicised
Cairo(950,450, 'outputs/reports_by_province.png')
barplot(outbreaks.summary$Provinces,names.arg=outbreaks.summary$Year,
ylab='Number of provinces reporting outbreaks', cex.axis=1.2, cex.names=1.2) ->
tmp
I can change the family, ie :
> par('family')
[1] "serif"
but Cairo doesn't seem to respect it (I'm actually wanting Helvetica so it
doesn't matter), but I can't fix the font (and I note from the docs:
fonts see pdf, ignored, Cairo automatically detects and embeds fonts
)
So I'm wondering if it is just my installation, a known issue or I've missed
the workaround (using CairoFonts hasn't changed it).
cheers
Beb
