I find a website called try R and it is sponsored by O'Reilly . It is very useful for beginner . I learn programming by the book before, but I still have problem in programming since there are too much words and it really take too much time to study all book . besides I am not familiar with English
But when I use try R , it really easy and helpful .so if you can make more website like this , it will really helpful to beginner . I search many website like try R in other programming language but try R is the best tutorial only ..
thanks for considering this idea ....
