You can interrupt the loop (e.g.. by pressing ESC), look at the results, and
then start it again.
e.g.
mumbo <- list()
for(jumbo in 1:1e+5000) {
mumbo[[jumbo]] <- do.many.time.consuming.things.with(jumbo)
}
# wait for a few days
# then press <ESC>
save(mumbo, file="head of mumbo")
# now restart it
for(jumbo in jumbo:1e+5000) {
mumbo[[jumbo]] <- do.many.time.consuming.things.with(jumbo)
}
