How to exclude packages for updating in R?

Question

I want to keep some packages downloaded from CRAN/Bioconductor in the older version while I could update other packages using commands like biocLite() .

How could I make a black list and tell R not to update specific packages?

Thanks!

Answer 1

You can prepare an "updatable" list of packages, then call biocLite

blacklist <- c("pkga", "pkgb")
installed <- rownames(installed.packages())
updatable <- installed[!installed %in% blacklist]
biocLite(updatable)
