There is one minor problem with parse(): if any of the individual commands
has an error, the entire text will be parsed in a single error.
For example, in a normal R console:
> print(2); ls(
So first print(2) is executed, and only after the console expects the user
to continue the command from ls(
Parsing the same text:
> parse(text = "print(2); ls(")
Error in parse(text = "print(2); ls(") :
<text>:2:0: unexpected end of input
1: print(2); ls(
What I would need is something to separate the two commands, irrespective
of their syntactical correctness:
 "print(2)" "ls("
I hope this explains the situation,
