alias is an useful command in Unix/Linux/MacOS env, which can effectively reduce the repeated commands.
system(“some command”) in R is a good way to make system calls within R, such as generate sequence data with seq-gen.
However, “some command” refers to system-default command, not aliased command, since Unix does not expand alias to non-interactive mode.
It’s very annoying when running jobs on server/cluster without root authorities.
So a good way in practice is to add full path to system function, something like system(”~/bin/some_program”)
