Dear R helpers

I have following table

Name                 no_of_instances                    
AAA                             12                                
AA                               17                                
A                                  0                                    
BBB                             11                                 
BB                                6                                  
B                                  0                                  
C                                  8                                  
D                                  3                                  

Now I need to generate the uniform random numbers (against the no. of instances) and assign these numbers generated against the respective names. E.g. I need to generate 12 random numbers and assign these numbers against AAA.

Individually I can generate them as

AAA_no = c(runif(12))
AA_no  = c(runif(17))
......

and so on.

And in the end I can club them as

ran_nos = c(AAA_no, AA_no, ..........D_no)  

My problem is if there are say 1000  names, then it will be a cumbersome job to generate 1000 individual random number sets and then to combine them to form a single dataset.

Is there any alternative to this?

Thanking in advance

With regards

Maithili
