I have two vignettes that I build externally because the required data sets are largish (20 and 40 MB zipped), so I provide them for download on hyperSpec's home page but do not want to burden CRAN with them. Instructions how to get that data to build the vignette yourself are one of the first points in the vignette. I do /not/ have BuildVignettes: FALSE but a Makefile that turns of pdflatex for these two only, and dummy .Rnw files that provide just the appropriate \VignetteIndex etc. entries. IMHO that is a perfectly reasonable option for FOSS packages, and while it makes it my responsibility to check the vignette building, a Makefile for preparing the package takes care of that as well. I can also make sure that both data and real vignette source are available there. For an upcoming spectral unmixing package, however, I'd like to include a vignette dealing with the cuprite AVIRIS data set (remote sensing data, a standard data set used on many publications for spectral unmixing) that can be downloaded from the NASA (http://aviris.jpl.nasa.gov/data/free_data.html). Is it acceptable to have a vignette that points to yet another data source (which is out of my control)? (I think this question goes mainly to Brian and the author of the part of the manual cited by Ben).
