Subject: [R] Problem with data frame

Dear r-users,

suppose I have n normal distributions with parameter N(0,i) i=1,2,.......,n
respectively.

Now I want to generate 500 random number for each distribution. And want to
put all 500*n random numbers
in a single data frame.

I tried with following code:

>n=20
random = data.frame(n)
for ( i in 2: length)
   {
    random[,i] = random(500,mean=0,sd=i)
   }

but while executing this I am getting errors.

Can anyone give me any suggestion?
Thanks and  regards
Arun
