[Bioc-devel] package size issue

[Jianhai Zhang]

Hello Boris and Herve,

Thanks for your suggestion!

I have checked out the size difference between pdf and html. The pdf vignette size is indeed much smaller, but pdf cannot use url to refer to online images. I have 90 images in the vignette. To reduce size, I hosted them on github and want to insert them via url. If I use pdf vignette I have to copy these images in local, and the final package size increases again.

Regards,
Jianhai

Interesting observation Boris.

The software packages currently have 1261 pdf vignettes and 983 html
vignettes in BioC 3.9. Here are some quick stats that confirm Boris'
observation (sizes are in bytes):

 > summary(pdf.sizes)
     Min.  1st Qu.   Median     Mean  3rd Qu.     Max.
     5267   156919   225146   454966   411965 26385420

 > summary(html.sizes)
     Min.  1st Qu.   Median     Mean  3rd Qu.     Max.
      663   641812   929989  1607509  1785061 83352286

 > length(pdf.sizes)
[1] 1261

 > length(html.sizes)
[1] 983

The pdf vignettes are almost 4x bigger than the html ones in average.
