I am trying to fit the chi-squared distribution to a set of data using the fitdistr function found in the MASS4 library, the data set is called ONES3, I have loaded it using the command ONES3<-read.table("ONES3.pdf",header=TRUE,na="NA") I print out the dataset ONES3 to the screen to make sure it has loaded Then I try to fit this data using the command fitdistr fitdistr(ONES3,"chi-squared") and it returns the comment Error in fitdistr(ONES3, "chi-squared") : 'x' must be a non-empty numeric vector
Can anybody help with this, I imagine it is a common mistake for beginners like myself audaces fortuna iuvat --------------------------------- [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
