Hi, I'm new to R language.

There is a problem I couldn't understand.

Hope you can answer my question.

 

when i type

 

>for (i in 1:10){

+     print(sample(9,4,replace=T))

+}

 

and it shows ten of four numbers

and how do I do to calculate the frequencies in each list?

 

I know there is a hint; list10<-vector(mode="list",length=4)

 

But I don't know how to use it.

How do I name each list?

 

There are my problems.

Thanks!!

 

Best Regards,

vie
