Hi
I have a problem using the package cluster on my binary data. I want to try mona at first. But i get the an error.
hc<-read.table("all.txt", header=TRUE, sep="\t", row.names=1) srt(hc) `data.frame': 51 obs. of 59 variables: $ G1p : int 2 1 1 1 1 1 1 1 1 1 ... $ G1q : int 1 1 1 1 1 1 1 1 1 1 ... $ G2p : int 1 1 1 1 1 1 1 1 1 1 ... $ G2q : int 1 1 1 1 1 1 1 1 1 1 ... $ G3p : int 1 1 1 1 1 1 1 1 1 1 ...
m<-mona(hc)
Error in mona(hc) : All variables must be binary (factor with 2 levels).
You have to be careful that the data are indeed each factors with 2 levels (numeric variables with values 1 and 2 will not do). A summary of the data will tell you that.

I find this strange when the cluster dataset "animals" have the same structure as my data.
srt(animals) `data.frame': 20 obs. of 6 variables: $ war: int 1 1 2 1 2 2 2 2 2 1 ... $ fly: int 1 2 1 1 1 1 2 2 1 2 ... $ ver: int 1 1 2 1 2 2 2 2 2 1 ... $ end: int 1 1 1 1 2 1 1 2 2 1 ... $ gro: int 2 2 1 1 2 2 2 1 2 1 ... $ hai: int 1 2 2 2 2 2 1 1 1 1 ...
m<-mona(animals) #works fine
what is this error trying to tell me? mvh morten
