I am trying to fit distribution for data consisting of 421 readings.It is basically no of requests arrived per minute.It contains many 0 entries as no of requests.When i use
I get following error:
Error in optim(x = c(0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, :

        initial value in 'vmmin' is not finite

What should I do ? I need this function because I want to get value of estimated parameters.
Is there any other function to perform such calculations? Please help me.
Thank You.

Code is as follows:
N<-data.frame((read.table("cs2ip.txt"))) attach(N)
