Several Basic Questions

Hello, everyone,

I am having several basic questions that I haven't found the answer to from
the manuals:

1. How to remove "[1]" when a single line message is printed?
2. How to print several variables (e.g., a character string and a numeric
variable) at the same line?
3. How to have the control of the accuracy of variables? e.g., in the
following,
[1] 1134567
I want variable to have an accuracy of 2 digits behind the decimal point
instead of all the digits behind the point being cut off.

Thank you in advance for any help.

These may not be explicit in the R manuals, but they are in all good books 
on R (see the FAQ).

Dear Prof. Ripley,

Thank you for your reply. It works fine except for question 3. I got

            

      
      
      
    

        
1134567

May variable z has been rounded to 0 digit behind the point at the very
beginning. How to avoid that?

Read the help on format (and print), especially its `digits' argument.
More generally, read the help pages on functions new to you!
