Quite often I have long procedures running and want to do this over night. However, my computer would still be running all night after the script has finished. This is easily circumvented by the following lines that I put at the end of such a script:

# set working dir
# setwd("C:/Users/Kay/Desktop")

# long procedure:
for(i in 1:1e+5) {cat(i); cat("\n..................\n")}

d <- "something"

# save history
savehistory()

# and worspace
save.image()

# then shutdown after 240 s
system("C:/Windows/system32/shutdown.exe -f -s -t 240")

# this would abort the shutdown:
# system("C:/Windows/system32/shutdown.exe -a")
