R: pass variable from R to unix -

i running r script via bash script , want return output of r script bash script keep working there.

the bash sth this:

#!/bin/bash rscript myrscript.r a=output_from_myrscript.r sth 

and r script sth this:

for(i in 1:5){ sink(type="message") } 

i want bash work 1 variable r @ time, meaning: bash receives i=1 , works that, when task done, receives i=2 , on.

any ideas how that?

one option make r script executable #!/usr/bin/env rscript (setting executable bit; e.g. chmod 0755 myrscript.r, chmod +x myrscript.r, etc...), , treat other command, e.g. assigning results array variable below:

myrscript.r

#!/usr/bin/env rscript cat(1:5, sep = "\n") 

mybashscript.sh

#!/bin/bash res=($(./myrscript.r)) elem in "${res[@]}"   echo elem "${elem}" done
