I noticed that when I run a long command in linux (I am using a cantos 7.3 distro, R 4.0.3 on the terminal) and that I pipe to head only the first outputs are shows to me (and the command stops)
ls -R /opt # on my system I would get tons of output for 10s of seconds
ls -R /opt | head # just get the top 5 and command is stopped straight away
when I try the equivalent in R I cannot get the same behaviour
system(command = "ls -R /opt | head") # will take a long time (I assume the time for ls -R /opt to finish)
Is there a way for me to get the same behaviour in R than the one I get on my system command line ?
