Here is a simple code to reinstall all the necessary R packages to keep you up and running. The script will check whether the required packages have been installed, if not, it will install them accordingly.

#create a function to check for installed packages and install them if they are not installed
install <- function(packages){
new.packages <- packages[!(packages %in% installed.packages()[, "Package"])]
if (length(new.packages))
install.packages(new.packages, dependencies = TRUE)
sapply(packages, require, character.only = TRUE)
}
required.packages <- c("package1", "package2" )
install(required.packages)
