Description Dan Keshet 2012-12-19 19:29:10 UTC
Running embedFonts on filenames with spaces results in an error, because the filename isn't escaped or quoted in the internal call to ghostscript.

Steps to reproduce:

1) Run embedFonts on a filename with spaces.

Actual results:

* Error is raised

Expected Results:

fonts embedded.

> embedFonts(file='../output/Two words/example.pdf')
Error: /undefinedfilename in (../output/Two)

It does not 'crash': see the R posting guide for the proper use of that word.

The short answr is 'don't do that' (on Linux: why?).  But shQuote() has been added.

There's a few reasons: 

1) I have a cross-platform development team and the developers on non-linux OSes prefer names with spaces.  As it works for them, they will have a hard time remembering not to use them.

2) Many of our filenames are generated automatically based on data structures, whose names are in turn imported from our data sources.  We like to keep the original names around so that they appear in a friendly way as graph labels; maintaining separate names for filenames and graph labels is certainly possible, but its unnecessary overhead except for this one call (before your fix).

Thank you!
