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.

Yes. Now I understand. There was one single variable among my 59, which did only have 1 level: I used summary(mydata) as you said:
and found
L16p Min. :1 1st Qu.:1 Median :1 Mean :1 3rd Qu.:1 Max. :1
I removed this and now it workes fine.... thanks alot for your quick reply regards greatful morten
