Dear List,
There seems to be an bug in compactPDF() or at least an inconsistency
with the documented behaviour.
Thanks, looks easy to fix. I'll make the correction. (A bit more below...)
The documentations states:
Details:
This by default makes use of ‘qpdf’, available from<URL:
http://qpdf.sourceforge.net/>, including a Windows binary. If
‘gs_cmd’ is non-empty, GhostScript is used.
I don't have qpdf on my system so planned to use ghostscript. However,
the code for compactPDF() has as it's first few lines:
if (!nzchar(Sys.which(qpdf)))
return()
So because I don't have qpdf, compactPDF() always returns NULL:
nzchar(Sys.which(Sys.getenv("R_QPDF", "qpdf")))
[1] FALSE
compactPDF("../analogue/pkg/inst/doc/analogue_methods.pdf", gs_cmd =
"/usr/bin/")
That won't work: you need the full path to the gs_cmd, not just its
home directory.
