It is difficult searching for previous posts about this since the keywords are short and ambiguous, so I hope this is not a duplicate question.

I can easily declare an array on the command line.

$ names=(X Y)
$ echo ${names[0]}

I am unable to do the same from within R.

> system("names=(X Y)")
sh: Syntax error: "(" unexpected

Reading the documentation for the system function, it appears to only be relevant for executing commands. What can I do instead to declare a BASH array ? Thanks.
