R-3.5.0 is installed here. When I tried to update installed packages

Reading ?update.packages() I did not see an option that would
automatically update dependences built under an earlier version of R. Is
there such an option that I missed?
I think you want update.packages(ask = FALSE, checkBuilt = TRUE) to
automatically update all packages and their dependencies. With the
default checkBuilt=FALSE, R just sees whether a dependency is a high
enough version number. But packages installed under R x.y.z are not
usable in R x.y+1.w.

Alternatively, is there a function I can run that will rebuild all
installed packages after I upgrade R versions?
