Thank you. This answers my question. I am using Linux, too.

Subject: [R] Declare BASH Array Using R System Function
Hello,
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]}
X
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.
