[R] search R vignettes

[Liviu Andronic]

Dear all,
To list all vignettes installed on my system, I would issue
`vignette(all = TRUE)'. But how can one search for a "topic" in all
vignettes available on CRAN?
One method was suggested here [1]---search on Google: `smth
filetype:pdf site:cran.r-project.org/doc/vignettes'---, but it does
not work. Would anyone know a page that mirrors all CRAN vignettes,
similar to this (rather outdated) one [2],  or perhaps some other way
to search for information in vignette .pdf files only?
Thank you,
Liviu
