Hi all,
Thank you for your help. The only original question I am still a bit
stuck on is #3. I read a lot about the command today, and tried
several approaches, but am unsure how to remove that warning.
* checking sizes of PDF files under ‘inst/doc’ ... WARNING
‘gs+qpdf’ made some significant size reductions:
compacted ‘ePort.pdf’ from 1655Kb to 1076Kb
consider running tools::compactPDF(gs_quality = "ebook") on these files
I work on a Mac with both RStudio and terminal (can do either). In
either RStudio or terminal, I could run the command:
compactPDF("inst/doc", qpdf = Sys.which(Sys.getenv("R_QPDF", "qpdf")),
gs_quality = "ebook")
I would not get any output from that. And when I then run:
check()
I noticed the WARNING was still there.
I also ran:
R CMD build --compact-vignettes=gs
But then when I ran check(), I still noticed the WARNING.
I also ran:
build(compact-vignettes("gs+qpdf"))
which gave me the error:
Error in inherits(x, "package") : object 'compact' not found
I tried a few other syntax I found online, but they mostly gave me warnings.
So, what I would love for any advice/input on, is what I can do to
remove that WARNING (if I must)? I am not sure if I am running
commands incorrectly, running in the wrong folder, should be using
command/Rstudio, etc. Even reading advice online and looking at the
documentation of build and compactPDF is not solving this for me (and
it may be due to my inexperience with R and terminal).
Thanks again for any help!!!
