Saving .pdf with symbols and italic font

[Aric Schultz]

Hi all, sorry if this has been answered before, but I haven't been able to find a suitable solution after quite a bit of googling.

I need to save figures as PDFs, with axis labels including both symbols and italic font. Rstudio won't save the symbols unless I use cairo_pdf(). But cairo_pdf won't save italic font...is there a way to have both. I'm trying to label discrete groups on the Y-axis: WT, WT∆myosin, WT∆myosin + MYOSIN etc...The journal I'm submitting to requires PDF figures, and gene knockouts (myosin in this case) need to be italicized. 

I've specified my labels as follows:

my.labels <- c(expression(paste("WT∆", italic('myosin')),

                       expression(paste("∆", italic('myosin'), '+MYOSIN'))

)

They look great until saving with cairo, then the italic formatting is lost.

Cheers,

Is this possibly of any help?

Hi thanks for your suggestion.

To anyone reading this it has been resolved.

The problem was in how I was specifying the delta symbol...

WRONG = expression(paste("WT∆", italic("myosin")))

RIGHT   =  expression(paste("WT", Delta, italic("myosin")))

Cheers,
