I wouldl ike to ask you if R supports step by step execution.  I have written 
some nested loops and  I would like to check on every  step what are the values 
of some variables. Printing all the variables  just creates a really big output 
of numbers.

Could you please give some debugging tutorial that included the aforementioned 
functionalities?


|Moreover can you please tell me how I can concatenate variables and strings so 
to print some debugging messages /
"The value of x is " + x + " and the value of y is " +y.


Best Regards
Alex
