Thank you for your reply.
My objective is simple. Assume I have a constant vector, say Vector. in
C++ code, I want to do:
int index;
cout<<"Please enter the index of the element you want to look at Vector :";
cin>>index
cout<<Vector[index]
I want every user to be able to do this.
As I understand, scan can only read data from a fixed file. Can I just
get the input from the shell directly?
Isn't that what the file argument of ?scan says? I think?
file: the name of a file to read data values from. If the
specified file is ‘""’, then input is taken from the keyboard
(or whatever ‘stdin()’ reads if input is redirected or R is
embedded).
