[R-sig-teaching] R exercices

[cgenolin]

Thanks for your answer.

Yes, it is quite different from what I am looking for which will be 
more
something like :

--- 8< -----

Exercice 1: wrote a function that compute the surface of a rectangle

Exercice 2: wrote a function that compute factorial n (whithout using 
the
function factorial)

Exercice 3: wrote a function, that given a n, will draw a triangle of 
"*".
Example with n=5

*
**
***
****
*****

--- 8< -----

The first exemple is about writing a (very) simple function and 
returning the result ; the second
need the use of a loop. The third will need two loops (for a beginer).

And so on, on various topic.
