[R] Problem with fitdistr function

Hello, I am using fitdistr function for parameter estimation. When I use fd<-fitdistr(V2,"gamma") 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 fd<-fitdistr(V2,"weibull") Error in optim(x = c(0L

[R] Error in optim while using fitdistr() function

Hello, 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 fd<-fitdistr(V2,"gamma") I get following error: Error in optim(x = c(0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L,

[R] How to fit discrete distribution to data in R having non standard shape?

Hello, I have 421 readings of time and no of requests coming at perticular time.Basically I have data with interval of one minute and corresponding no of requests arriving per minute.It is discrete in nature.I am collecting data from 9AM to 4PM.But some of readings are coming as 0.When I plotted h

[R] Does goodfit() require frequency count of the numbers or numbers themselves?

Hello, I am a student and for project I need R. I have one problem regarding function goodfit(). Does goodfit() require frequency count of numbers or numbers themselves? For example suppose I have data say 150 readings.Do I need to use goodfit() directly on data or should I make suitable no of bin
