I've tried with system2 added on the first line, so:
Example.R:
system2('ls', timeout=5)
cat('Start non-interruptable functions\n')

sample_b <- sample(1:2e7)
matching <- match(sample_a, sample_b)
cat('Finished\n')
Sys.sleep(10)
And in terminal/bash:

source('Example.R')
Send ^C between the messages (Start... until Finished)
Or if you have a more powerful CPU you can increa...

...ent whether I?m in a clean session (in which case some time is allowed to pass, so that when the function returns the script can be interrupted), or whether I have called base::system() or system2() with timeout other than 0.
Reproducible example:
cat('Start non-interruptable functions\n')
sample_a <- sample(1:1e7)
sample_b <- sample(1:2e7)
matching <- match(sample_a, sample_b)
cat('Finished\n')
Sys.sleep(10)
Observed behaviour:
In a clean session, when I hit Ctrl-C during the execution of match, there is a delay, and as soon as Sys.sleep() is invoked, the script is interrup...
