[From my gist] How to renew R in Windows

post date: 2020-4-3

for Windows

• run the sentences below in R install.packages("installr") require(installr) updateR()

• then there will be a interactive window

• choose a path to install the new R (not the old path)
• allow to copy the packages from old R to new R
• allow to update all packages
• allow other transactions

• finish the window

• finally

• delete the old R folder (unless you want to keep it)
• add the new R bin path into environment Path
• if you use RKernal in jupyter, run in R IRkernel::installspec()
