about lable changes in file format

[lily li]

Hi ggplot2 users,

I'm drawing figures, using the ggplot2 function. When there are per mil sign (‰) in the x or y-axis, and when I save the figure as a PDF file, the per mil sign becomes (...). How to solve this problem? The figures are definitely clearer when saved as PDF rather than tiff/jpg/etc format. Thanks for your help.

Can you pass another encoding to `pdf.options()`? My guess would be pdf is using some sort of encoding (from your system?) which doesn't support all relevant characters. I recommend using "UTF-8", e.g. `pdf.options(encoding = "UTF-8")`.

Cheers,

Roman

Thanks for your reply. I just clicked on the Export button in the lower right panel of the R-studio. It has two options only, Save as image, or Save Plot as PDF. So I couldn't set other details. Do you mean to save the file in the console?

For my needs (also printing "weird characters" like ščž) using `ggsave` in the console works flawlessly. I'm on Windows.

Cheers,

My experiences have been that ‘ggsave’ does work for per mill notation on Windows but not on OS X. On OS X the only workaround I’ve been successful with is using Cairo. I tried changing the encoding on OS X but got:

 

‘Error in grDevices::pdf(..., version = version) :

  failed to load default encoding

In addition: Warning message:

  In grDevices::pdf(..., version = version) :

  failed to load encoding file 'UTF-8'’

 

Example attached.

Actually, I still have another problem. For example, I want to inset one plot to another, and save the whole as pdf file.

require(grid)

print(ggplot1.1)

print(ggplot1.2, vp=viewport(.6, .3, .5, .5) #viewport(x-location, y-location, width, height)

cairo_pdf('~/figuredoc/figure1.pdf')

But the saved file is only ggplot1.2. That is why I use the Export button to save the figure initially, so it will save the whole thing. Thanks again.
