R - upgrade all packages

  • How to upgrade R?

There is this package, which you can use .... but you must have it installed before new version of R come ;-) - otherwise it is typical "catch 22":
Upgrade from 3.3.1  to 3.3.2 :
install.packages('installr', repos = '') 
Warning message: 
package ‘installr’ is not available (for R version 3.3.1)

So basically - instead this go to and update using new R.

  • How to upgrade all your existing R packages (libraries)?

Use this command to upgrade all existing packages:

  pkgs =[1]), stringsAsFactors=FALSE)$Package,
  type = 'source'
And quick update - to the article ;-) - use this instead:

update.packages(ask = FALSE, dependencies = c('Suggests'))

Have a fun!
