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
