Re: [R] fit lognorm to cdf data

Hi I thought that fitdistr is used when I have original data, something like dat <- rlnorm(1000) but I have just five values (proc, size) as showed in my example. Actually those data are similar like results from sieving for which I can use package sievetest but as they do not follow Rosin Ram

Re: [R] Help documentation of "The Studentized range Distribution"

Dear Peter and Jeff, I admit I was not precise in what I really wanted. It was more a report that the documentation is confusing, than really asking for help. Still, I was only 97% sure that it was not my fault, so I remained cautious. So, my suggestion would be to say under the header usage ju

Re: [R] fit lognorm to cdf data

* fitdistr? * it seems unusual (to me) to fit directly to the data with lognormal... fitting a normal to the log of the data seems more in keeping with the assumptions associated with that distribution. -- Sent from my phone. Please excuse my brevity. On July 10, 2017 7:27:47 AM PDT, PIKAL Pet

Hi Sema, read.csv2 use ',' as the decimal separator. Since '.' is used in your file, everything becomes a character which in turn makes pam complain that what you pass to the function isn't numeric. Use read.csv2("data.csv", dec = ".") and it should work. You can also use class(d) to check the c

Well, it is clear enough that the problem is in interpreting the documentation. However, when you claim you tested something, and found it inconsistent with tables, it would be advisable to back it up with examples! The description in the help files and in the sources is admittedly confusing. T
