[Bioc-devel] Issues with package size

Hi Hervé, Hi all,
Yes, I totally understand and agree with the standard of Bioc packages
development. I always try to follow it as best as I can. But regarding the
"real rerunnable vignettes", I think there are several scenarios that make
it really difficult to follow this standard way:
1. Some examples need a long time to run or depend on a very large dataset,
and it is impossible to use a reduced small subset of data. E.g. in my
HilbertCurve package, there are several examples visualizing the complete
chromosome 21 (around 15 examples, which take almost 30-45 min to run).
Because this package makes a "global view of a genome", it makes no sense
to only work on a small subset of genomic regions. My solution is on my
local machine, the code chunks that generate these plots are actually
evaluated and they also generate cached figures, while on the Bioc server,
the code chunks are not evaluated and the cached figures are directly used.
I guess packages for single-cell RNAseq analysis might also have this issue
that the analysis makes sense only with more than thousands of cells (just
guess, I don't have experience with scRNAseq data analysis).
2. Some vignettes generate or include many figures (static or gif) which
results in the final file size of the package being very huge (tens of MBs
or maybe more), especially for packages focused on data visualization. A
good vignette should contain lots of example figures which illustrate the
various usages of the package for users. E.g. my ComplexHeatmap package
contains hundreds of figures, thus I decided to host the vignette somewhere
I can think of some solutions for this:
1. include a small and evaluable vignette that only contains the "core
analysis" or "the most used features" in the package, while hosting more
comprehensive vignettes somewhere else.
2. add extensive tests in the package to ensure the reliability of the
package. For example, in ComplexHeatmap, although there is almost no
runnable vignette, it actually includes hundreds of tests that will be
evaluated during `R CMD check`.
